HEPATITIS B VIRUS SURFACE ANTIBODY (087-7201)

  HBA

 Enchanced chemiluminescence - EIA (OCD 3600)

 Chemistry

  24 - 72 hours

Collect: Routine venipuncture, SST (serum separator tube)

Storage/Transport:  Centrifuge the specimen and store at 2-8°C.

Causes for Rejection: Gross hemolysis, specimens containing particulate matter, heat-inactivated specimens

If applicable, state clinical information that is required to be provided with specimen.

By report (reports may vary based on instrumentation, patient age and sex)

 This test is used to evaluate response to immunization and resolution of hepatitis disease. If the patient has no detectable antibody, it is recommended to wait three months before testing again. Tests on samples collected less than three months from the initial results will be cancelled, unless approved by a Microbiology Director or their designee. If "indeterminate", the assay is unable to determine if antibody to Hepatitis B surface antigen is present at levels consistent with immunity.  Patient's immune status should be assessed with other clinical information and/or retesting in 4-6 weeks if clinically indicated.

Recommended tests to determine acute hepatitis (see Note) are Hepatitis A virus antibody IgM, Hepatitis B Surface antigen, Hepatitis B Core antibody IgM and Hepatitis C virus antibody.
NOTE: Limited Coverage Test (NCD)

Recommended tests to determine chronic hepatitis are Hepatitis B Surface antigen, Hepatitis B Core antibody IgM and Hepatitis C virus antibody.

When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient.  Components of the organ or disease panels may be ordered individually.  The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-9 code or its verbal equivalent.
