Hepatitis A IgM Antibody EIA
Blood should be collected in a plastic, sterile STD Program approved collection tube. Please follow the manufacturer's instructions on clot time and centrifuge speed/time requirements.
The Virology Lab 96 form must be filled out completely. The following information must be included on the form:
Specimens should be shipped refrigerated (2-8ºC) within 48 hours of collection. For longer storage, specimens must be frozen at -20ºC or colder. Frozen specimens must be shipped on dry ice and received at a temperature of -20ºC or colder.
Diagnosis of an infectious disease should not be established on the basis of a single test result. Detection of anti-HAV IgM does not necessarily imply an acute HAV infection due to the longevity of anti-HAV IgM. The detection of anti-HAV IgM can be useful for the differential diagnosis of hepatitis A from other forms of viral hepatitis. Any diagnosis should take into consideration the patient's clinical history and symptoms, as well as other laboratory data. Patients with specimens exhibiting borderline results should be retested at approximately two week intervals. A reactive anti-HAV IgM result does not exclude co-infection by another hepatitis virus. A non-reactive result does not exclude the possibility of infection with hepatitis A virus. Levels of Anti-HAV IgM may be below the cutoff in early infection. The performancce of the MONOLISA™ Anti-HAV IgM EIA has not been established with immunosuppressed or immunocompromised patients, cord blood, neonatal specimens, cadaveric specimens, heat-inactivated specimens, or body fluids other than serum or plasma, such as saliva, urine, amniotic, or pleural fluids.
