Cytomegalovirus (CMV)<\/h4>\n\n\n\n
\n

Cytomegalovirus (CMV) antibody screen is run 3 times daily on Monday through Friday. The antibody screen is a qualitative detection of CMV IgG class antibodies in human sera by the FDA approved Zeus ELISA (enzyme-linked immunosorbent assay) test system.<\/p>\n\n\n\n

Epstein Barr Virus (EBV)<\/h4>\n\n\n\n
\n

Epstein-Barr Virus virus detection is run 3 times daily on Monday through Friday and is the qualitative detection of Epstein-Barr virus (EBV) Viral Capsid Antigen (VCA) IgG, VCA IgM, and Nuclear Antigen (EBNA) IgG class antibodies in human sera by the FDA approved Zeus ELISA (enzyme-linked immunosorbent assay) test system. Results are reported as either Reactive, Equivocal or NON-reactive.<\/p>\n\n\n\n

Hepatitis A<\/h4>\n\n\n\n
\n

shedding occurs in the weeks before clinical symptoms appear. Hepatitis A antibody testing is performed 2 times daily, Monday through Friday; IgM antibody tests are performed on all reactive specimens. Hepatitis A IgM indicates acute infection. All positive Hepatitis A IgM results are called to the requesting physician or laboratory and the local King County Dept. of Health. The physician must also report acute Hepatitis A infections to the local County Department of Public Health (in King County, telephone the Communicable Disease Department at (206) 296-4774). For vaccine recipients a Hepatitis A vaccine screen can be ordered. This assay does not include IgG\/IgM differentiation if positive.<\/p>\n\n\n\n

Hepatitis B<\/h4>\n\n\n\n
\n

Hepatitis B is transmitted through blood or secretions of infected patients. Infectivity of a patient is determined by enzyme immunoassay for Hepatitis B surface antigen (HBsAg), which is run Monday through Friday. Reports of reactive HBsAg are called to the ordering physician or laboratory and are automatically run for Hepatitis B viral DNA by PCR. Patients with needle sticks and other parenteral exposures need to receive Hepatitis B Immune Globulin within 72 hours of exposure. The routine HBsAg run can accommodate most specimens generated by accidental parenteral exposure. The physician must also report acute Hepatitis B infections to the local County Department of Public Health (in King County, telephone the Communicable Disease Department at (206) 296-4774).<\/p>\n\n\n\n

Note: Positive HBsAg will reflex to a Hepatitis B DNA by PCR at an additional charge.<\/p>\n\n\n\n

Hepatitis B Surface Antibody & Hepatitis B Core Antibody<\/h4>\n\n\n\n
\n

Hepatitis B surface antibody (anti-HBs) and Hepatitis B core antibody (anti-HBc) assays are useful for identifying persons susceptible to Hepatitis B infection (i.e. needle stick exposures), for documenting persons with past infection with Hepatitis B virus, for vaccine screening, and for determining response to vaccination. The Hepatitis B surface antibody result is reported international units (I.U.) of Hepatitis B surface antibody. Values above a test standard containing 10 I.U. of Hepatitis B surface antibody are considered protective levels. Vaccination\/re-vaccination is warranted with values below this level. Anti-HBs assays and anti-HBc assays are performed daily Monday through Friday.<\/p>\n\n\n\n

Hepatitis B Core IgM Antibodies<\/h4>\n\n\n\n
\n

Presence of Hepatitis B core IgM antibodies helps to distinguish chronic carriers of HBsAg from acute cases of Hepatitis B. Persons with recent exposure to Hepatitis B will be reactive for core IgM, while chronic carriers of HBsAg will not. This test is sent out to a Reference lab.<\/p>\n\n\n\n

Hepatitis A & B Battery<\/h4>\n\n\n\n
\n

Hepatitis A & B Battery consists of the HBsAg, anti-HBs, anti-HBc and anti-Hep A tests. The laboratory requires 3-5 mL clotted blood or 1-2 mL of sera for the full battery.<\/p>\n\n\n\n

Note: A positive HBsAg reflexes to a Hepatitis B by PCR, quant. at an additional charge.<\/p>\n\n\n\n

Hepatitis B ‘e’ Antigen and Antibody<\/h4>\n\n\n\n

The Qualitative detection of Hepatitis B virus \u201ce\u201d antigen (HBeAg) and Hepatitis B virus \u201ce\u201d antibody (HBeAb) in human sera by the FDA approved DiaSorin Diagnostic HBe enzyme immunoassay (EIA).<\/p>\n\n\n\n

The presence of HBeAg in serum is associated with presence of Dane particles and Hepatitis B virus (HBV) DNA polymerase enzyme. These markers suggest active HBV replication. Hepatitis B Surface antigen (HBsAg) positive and HBeAg positive persons are much more likely to transmit infections to others. The development of anti-HBe during acute Hepatitis B infection is a marker of resolution of illness.<\/p>\n\n\n\n

Hepatitis C Virus (HCV)<\/h4>\n\n\n\n
\n

Hepatitis C is the leading cause of post transfusion hepatitis and of \u201cnon-A, non-B\u201d hepatitis. It may be acquired by blood products or by non-parenteral routes. Most HCV infections are sub-clinical, and chronic hepatitis is common. All positive Hepatitis C antibodies are confirmed by PCR at an additional charge. Hepatitis C Antibody screens are run daily, Mon. \u2013 Sat.<\/p>\n\n\n\n
