Hepatitis B Virus (HBV) Screening and Diagnosis (Triple Panel)

CPT 86704; 86706; 87340

Test Details

Methodology

Immunochemiluminometric assay (ICMA)

Result Turnaround Time

1 - 2 days

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Test Includes

Hepatitis B Surface Antigen (HBsAg) Screen; Hepatitis B Surface Antibody (anti-HBs); Hepatitis B Core Antibody, Total (anti-HBc); reflexes to Hepatitis B Core Antibody, IgM (IgM anti-Hbc) when indicated

Reflex criteria: If Hepatitis B Core Antibody, Total [006718] is positive and Hepatitis B Surface Antibody, Qualitative [006395] is non-reactive (NR), reflexes to Hepatitis B Core Antibody, IgM [016881]

Use

This is a triple test panel intended for screening and diagnosis of hepatitis B virus (HBV) infection. This panel can be used to identify different phases of HBV infection and to determine whether a patient has acute or chronic HBV infection, is immune to HBV as a result of prior infection or vaccination, or is susceptible to infection. This panel aligns with current CDC recommendations for HBV screening and testing.

Special Instructions

If reflex test is performed, additional charges/CPT code(s) may apply.

This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.

Limitations

The performance of the assays included in this panel has not been established with cadaveric specimens, heat-inactivated specimens or body fluids other than serum and EDTA plasma.

Custom Additional Information

Hepatitis B surface antigen (HBsAg) is a protein on the surface of hepatitis B virus that can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious. HBsAg can typically be detected in an infected person's blood an average of 4 weeks (range: 1-9 weeks) after exposure to the virus. Persistence of HBsAg, without anti-HBs, with combinations of positivity of anti-HBc, HbeAg, or anti-HBe indicates infectivity and the need for investigation for chronic persistent or chronic aggressive hepatitis.

The presence of Hepatitis B surface antibody (anti-HBs) is generally interpreted as indicating recovery and immunity from hepatitis B virus infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.

Total hepatitis B core antibody (anti-HBc) appears at the onset of symptoms in acute hepatitis B and persists for life. The presence of anti-HBc indicates previous or ongoing infection with hepatitis B virus in an undefined time frame. IgM antibody to hepatitis B core antigen (IgM anti-HBc) positivity indicates recent infection with hepatitis B virus (< 6 months) and its presence is consistent with acute infection.
