HelpTest Code LAB868 Hepatitis C Antibody, Total (IgG and IgM), Plasma or Serum
Infectious
Reporting Title
Hepatitis C Antibody
Methodology
Roche Diagnostics Electrochemiluminescence Immunoassay
This test detects IgG and IgM antibodies, but does not distinguish between them.
A positive result indicates that patient has been infected with hepatitis C virus (HCV), may harbor infectious HCV, and may be capable of transmitting disease.
Performing Laboratory
OhioHealth Laboratory Services-RMH Special Testing
Specimen Requirements
Serum
Draw blood in a gold-top serum gel tube(s). Spin down and send 1 mL of serum refrigerated. A speckled-top serum gel tube (s) or a plain, red-top tube(s) is also acceptable.
Alternate: Plasma - Lithium Heparin and EDTA
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Serum | Refrigerated | 21 days |
| Ambient | 3 days | |
| Frozen | 3 months |
Specimen Transport Temperature
Refrigerate: OK
Ambient: OK
Frozen: OK
Reference Values
Negative
A negative result does not exclude possibility of infection with HCV. Negative results may be due to antibody levels below limit of detection or to lack of response to antigen used in assay. Patients may have vector or fusion protein antibodies which could cause a false-positive result. Additionally, more specific tests may be useful in defining true HCV infection.
