The Anti-double stranded DNA (anti-dsDNA) test is one of a group of autoantibodies called antinuclear antibodies (ANA). Normally, antibodies protect against infection, but autoantibodies are produced when a person's immune system fails to adequately distinguish between "self" and "non-self." They mistakenly attack the body's own healthy cells, causing tissue and organ damage. Anti-dsDNA specifically targets the genetic material (DNA) found in the nucleus of a cell, hence the name "anti-dsDNA." The anti-dsDNA test identifies the presence of these autoantibodies in the blood. it used to help diagnose lupus.

TEST CATEGORY: cancer
CPT Code: 80047-80081
What is being tested?
Cancer antigen 15-3 (CA 15-3) is an epitope (antigenic determinant) present on a mucin-type high molecular weight glycoprotein (episialin) expressed on the apical surface of mammary gland epithelial cells. It is encoded by the MUC-1 gene. A normal product of breast tissue, CA 15-3 is overexpressed during the growth phase of certain breast cancers and shed into the circulation. Measurement of CA 15-3 can be used as a tumor marker for surveillance of patients diagnosed with breast cancer. Serial determinations are used to monitor primary treatment of disease and have the potential to detect early recurrence. It is important to note that although increased levels of CA 15-3 are associated with breast cancer, they can also be found in apparent healthy individuals (~5%), benign diseases, and other malignant conditions thus indicating a lack of specificity for breast cancer (Wiley, ASCP 2008).

B-type natriuretic peptide (BNP) and N-terminal pro b-type natriuretic peptide (NTproBNP) are peptide (small proteins) that are either hormones or part of the peptide that contained the hormone at one time. They are continually produced in small quantities in the heart and released in larger quantities when the heart senses that it needs to work harder. This supports fluid retention and volume expansion in the arteries and veins. Subsequently, the heart muscle is stretched and works hard to pump blood under normal resting condition. Tests for BNP and NT-proBNP measure their levels in the blood in order to detect and evaluate heart failure. The two tests are not interchangeable and should not be used together. Your healthcare practitioner should order one or the other but not both.

Factor XII is a ~80 kDa proenzyme synthesized in the liver with a half-life of approximately 50 to 70 hours. Factor XII, prekallikrein (PK), high molecular weight kininogen (HK), and C1 esterase inhibitor (C1INH) comprise the contact activation system (or pathway). Activated factor XII (XIIa), a serine protease, is the first component in the intrinsic coagulation pathway. In vitro, factor XII is activated (auto-activation) by negatively charged surfaces (such as kaolin, glass, dextran sulfate, ellagic acid, or celite) as well as a number of biologic substances. In vivo, factor XII is activated (hetero-activation) by some biological products of disease states (such as long chain polyphosphates, aggregated protein, and vascular collagen); however, full activation requires contact with a negatively charged surface in the presence of PK and HK. C1INH is the principle inhibitor of FXII. Deficiencies in Factor XII result in a prolonged aPTT. Unless combined with deficiencies of other coagulation factors, the PT and bleeding time will generally be within normal limits.

Adrenocorticotropic hormone (ACTH or corticotropin) is a polypeptide hormone produced and secreted by the anterior pituitary gland. ACTH is the second step in the hypothalamic-pituitary-adrenal axis (HPA), the coordinated stimulatory and inhibitory connections between corticotropin-releasing hormone (CRH), ACTH, and cortisol. ACTH functions to stimulate cortisol secretion from the adrenal glands and regulate cortisol levels. ACTH levels may be elevated in the presence of a pituitary adenoma (oversecretion of ACTH; Cushing disease), an ectopic ACTH-secreting tumor (eg, small cell lung cancer) or in primary adrenal insufficiency (cortisol deficiency resulting in chronically elevated ACTH levels; Addison disease). ACTH levels may be decreased in the presence of exogenous corticosteroid use, excessive cortisol production (Cushing syndrome), or pituitary/hypothalamic insufficiency. In the presence of a healthy HPA axis, ACTH levels follow a circadian pattern, rising at 4 AM (0400) with a peak at approximately 7 AM (0700). ACTH levels reach their nadir between 10 PM (2200) and 11 PM (2300). Interpretation of ACTH levels relies on correlation with concurrently collected blood cortisol levels.

What is being tested?
Estrone (E1), estradiol (E2), and estriol (E3) are the three major forms of estrogen. Of these, estradiol (E2) is the most potent endogenous estrogen followed by estrone and then estriol. Estriol (E3) is the major estrogen of pregnancy. It is produced by the fetus and placenta through a series of pathways. The fetal adrenals convert cholesterol to dihydroepiandrosterone sulfate (DHEAS). DHEAS is then converted to α-hydroxydehydroepiandrosterone by the fetal liver. Finally, α-hydroxydehydroepiandrosterone is converted to estriol in the placenta and diffuses into the maternal circulation. As the half-life of unconjugated E3 (uE3) is 20 to 30 minutes in the maternal circulation (maternal liver quickly conjugates for water-soluble urinary excretion), measurement offers timely evaluation of current fetal status.

Sex hormone binding globulin (SHBG) is a glycoprotein synthesized in the liver under the positive control of estrogens and thyroid hormones and suppressed by androgens. SHBG binds tightly to testosterone, dihydrotestosterone (DHT), and estradiol (a form of estrogen) in the bloodstream (45% to 65% of circulating sex hormones), with most of the remaining sex hormones weakly and reversibly bound to albumin. Only 1% to 2% of sex hormones circulate in the free, bioavailable state and are readily available to tissues (AACC 2019). Due to the higher affinity of SHBG for testosterone and DHT as compared to estradiol, SHBG also has effects on the balance between bioavailable androgens and estrogens (Mayo 2020).

Testosterone is the main sex hormone (androgen) in men. It is responsible for male physical characteristics. Although it is considered to be a "male" sex hormone, it is present in the blood of both men and women. This test measures the level of testosterone in the blood. Testosterone is mainly produced by special endocrine tissue (the Leydig cells) in the male testicles. It is also produced by the adrenal glands in both males and females and, in small amounts, by the ovaries in females.

Complement component 3 (C3), a protein produced in the liver, is an integral part of the immune system. It functions as an acute phase reactant and a central point in the activation of the complement pathways (classical, alternative, and MBLectin). Although increase of C3 can be detected in an acute response, it is of clinical interest when levels are decreased as seen with congenital C3 deficiency or with immunologic disease when complement is consumed at an increased rate. Conditions include chronic hepatitis, certain chronic infections (including hepatitis C virus associated cryoglobulinemic vasculitis), immune complex disease, poststreptococcal and membranoproliferative glomerulonephritis, and others. It is especially useful to assess disease activity in lupus erythematosus.

Complement component 4 (C4) is a protein produced mainly in the liver and, to a lesser extent, by other cells such as macrophages and monocytes. Components of the complement system have an important role in the inflammatory response and the removal of foreign cells. Complement activation has a number of physiological outcomes including: lysis of invading cells, enhancement of phagocytosis, clearance of immune complexes, increased vascular permeability, recruitment of neutrophils and monocytes, and amplification of the immune response. C4 levels can be sensitive indicators of disease, particularly SLE and proliferative glomerulonephritis disease activity.

Helicobacter pylori is a spiral-shaped gram-negative bacillus, for which the natural reservoir is the gastrointestinal tract of humans. The organism is unique in its ability to survive the acidic pH of gastric fluids. Although most infected individuals will not develop clinically significant complications, infection with this organism has been associated with increased risk of developing duodenal and gastric ulcers, non-ulcer dyspepsia, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. To detect infection, either an invasive (requiring endoscopy) or noninvasive testing algorithm is recommended based on patient demographics and symptoms. The urea breath test (UBT) is recommended as a first-line, noninvasive test for the diagnosis of a Helicobacter pylori infection. The simplicity and duration of the testing, which can be performed in the health care provider's office, makes this an agreeable test for both health care provider and patient. There are two types of UBT tests: Nonradioactive 13C test and radioactive 14C test. Both can be performed in 15 to 20 minutes and have similar cost and accuracy. Although the dose of radiation in the 14C assay is minimal, the trend is nonradioactive testing and, as such, is the emphasis of information contained in this monograph. The assay indirectly detects the presence of H. pylori-associated urease by measuring the patient's breath. Urease produced by the organism catalyzes decomposition of ingested, synthetic urea (13C-urea) subsequently releasing carbon dioxide (13CO2) which is measured in exhaled air. The UBT is positive if a current infection exists. This test can be used in initial diagnosis of infection and post-therapy confirmation of organism eradication.

Hepatitis C virus (HCV) is a small, enveloped, single-stranded RNA virus transmitted primarily through contact with infected blood (sharing needles, inadequately cleaned equipment) and, less commonly, through sexual contact or childbirth. Prior to 1992, which marked the onset of widespread screening of the blood supply in the United States, HCV was also commonly spread through blood transfusions and organ transplants.
HCV infection can be either “acute” or “chronic.” Acute HCV infection presents as a short-term illness occurring within the first 6 months after exposure to HCV. It is clinically symptomatic in only ~15% of cases and diagnosis is infrequently made. The majority of acute infections (>60% to 80%) lead to a slowly progressive chronic infection which is often asymptomatic but can result in cirrhosis (20% to 30% incidence after >20 years infection), hepatocellular carcinoma, or even death (CDC, 2013; Sacher, 2000). At present, HCV is the most common cause of chronic hepatitis and the most common reason for liver transplantation in the US (Huffman, 2014).
Molecular tests, also known as nucleic acid tests, are used to confirm a positive screening HCV antibody test by detecting HCV RNA in the blood (CDC, 2013). Molecular tests provide critical prognostic information for guiding treatment and measuring the response to antiviral therapy (Scott, 2007).

Hepatitis A virus (HAV) is a single-stranded, nonenveloped RNA enterovirus of the Picornaviridae family. It causes an acute, self-limited disease transmitted almost exclusively through the fecal-oral route; symptoms include fever, jaundice, anorexia, and diarrhea. Humans appear to be the only reservoir for this virus, and viral replication depends on hepatocyte uptake and synthesis, with assembly occurring only in liver cells (CDC, 2013).
Laboratory diagnosis of acute infection is typically made via the detection of IgM antibody to HAV at the onset of clinical symptoms or within 3-6 months of infection. Past evidence of HAV infection, or immunity, is determined using IgG-specific HAV antibody (rarely ordered or available), or total (IgG + IgM) HAV antibody. Total HAV antibody is also ordered by health care providers as a screen when assessing hepatitis-like symptoms.

There are seven confirmed genotypes of HCV known as genotypes one to seven; however much of the literature refers to 6 (1-6) major genotypes. Genotype prevalence varies based on geographic location, race, and mode of transmission (eg, IV drug use, maternal-fetal transmission, multiple sex partners, etc.). In the US, approximately 70% of cases are due to genotype 1 (the majority type 1a) and 20% are genotype 2. Genotype determination (which should be performed prior to therapy) guides treatment as some viral genotypes respond better to treatment than others.

Infection with either herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2) is common in the United States. Overall seroprevalence in 2015-2016 was 48% for HSV-1 and 12% for HSV-2 among people 14 to 49 years old. However, seroprevalence was much higher in some ethnicities: 72% for HSV-1 among Mexican-Americans (though only 9% for HSV-2) and 35% for HSV-2 among non-Hispanic blacks.
Seropositivity does not necessarily indicate the site of infection, but HSV-1 most often causes oral herpes and HSV-2 most often causes genital herpes. However, HSV-1 is responsible for an increasing proportion of primary genital infections; in some populations (eg, college students, young women), HSV-1 has been reported to account for over half of genital herpes infections.
Genital infections may be associated with small, painful lesions affecting anogenital areas as well as generalized symptoms such as fever, muscle aches, and malaise. However, most genital herpes infections are transmitted by individuals who do not know they are infected, as symptoms are often mild or absent.
Genital HSV-1 and HSV-2 infections can also cause neonatal herpes, especially among women who acquire genital herpes near the time of delivery.2 If genital herpetic lesions are present at the onset of delivery, cesarean delivery should be considered to prevent neonatal infection. Newborns exposed to HSV during birth should be followed closely with consideration of antiviral therapy.
Diagnosing infection and determining HSV type can indicate risk of disease recurrence, transmission risks, and prognosis (Table). However, the pathogenesis of herpes infection can make diagnosis difficult, as antibodies and nucleic acids are measurable at different points of pathogenesis (Figure 1). Many laboratory methods, such as viral culture, polymerase chain reaction (PCR), and antibody (serologic) testing, are available to address this difficulty. This Clinical Focus discusses the testing options available for the diagnosis and management of genital HSV infections.

The typhus fever group includes R typhi (murine typhus; endemic typhus) and R prowazekii (epidemic typhus). R rickettsiae is the most common rickettsial species encountered in the United States and is transmitted through a tick vector (Dermacentor species or, less commonly, Rhipicephalus sanguineus). Following a 2- to 14-day incubation period, patients most commonly present with fever, chills, and myalgia. A maculopapular rash typically appears 2 to 5 days after fever onset, though approximately 10% of patients will not develop a rash. Antibodies to the spotted fever group agents are detectable within 7 to 10 days after illness onset. Demonstration of either 1) seroconversion or 2) a 4-fold change in IgG-specific antibody titers in acute and convalescent serum samples is consistent with acute or ongoing disease.

Evaluation for fecal leukocytes is a part of the initial evaluation of diarrhea (Donowitz 1995). In general, the presence of fecal leukocytes indicates evidence of infection or inflammation such that further evaluation may be necessary (eg, stool culture for enteric pathogens, evaluation for ova and parasites, Clostridioides difficile (formerly Clostridium difficile) testing, and/or colonoscopy). Absence of fecal leukocytes does not exclude bacterial diarrhea or the need for stool culture.

Fibrinogen (Factor I) is the most abundant coagulation protein (about 2% of the total plasma proteins) and has an essential role in coagulation. It is converted into fibrin by thrombin and forms the fibrin clot by covalent cross-linking. Fibrinogen also plays a role in platelet function and contributes to blood viscosity. Fibrinogen levels <100 mg/dL can be associated with spontaneous bleeding. Acquired decreases in fibrinogen (eg, with liver dysfunction or DIC) are much more common than hereditary deficiencies; however, both can result in impaired coagulation and thrombotic events.

C-reactive protein (CRP) is a protein that increases in the blood with inflammation and infection as well as following a heart attack, surgery, or trauma. Studies have suggested that a persistent low level of inflammation plays a major role in atherosclerosis, the narrowing of blood vessels due to build-up of cholesterol and other lipids, which is often associated with cardiovascular disease (CVD). The hs-CRP test accurately measures low levels of CRP to identify low but persistent levels of inflammation and thus helps predict a person's risk of developing CVD.
