Reference Ranges
Hepatitis A IgM Antibody
| HAVAB - Initial Testing | ||
|---|---|---|
| Cut-off Index (COI) | Result | Retest Procedure |
| <0.90 | Non-reactive (negative) | Retesting not required |
| ≥0.90 to <1.10 | Borderline | Retest in duplicate |
| ≥1.10 | Reactive (positive) | Retesting not required |
| HAVAB - Repeat Testing | ||
|---|---|---|
| COI after retest | Final Result | Interpretation |
| 2 of the 3 results are <1.0 | Non-reactive | Negative for HAV IgM antibodies. |
| 2 of the 3 results are ≥1.0 | Reactive | Positive for HAV IgM antibodies. |
| 2 of the 3 results are between ≥0.90 to <1.10 | Borderline | It is recommended that a specimen be drawn in two weeks and retested. |

Hepatitis B Surface Antigen
| HBSAG - Initial Testing | |||
|---|---|---|---|
| Cut-off Index (COI) | Qualitative Result | Interpretation | Retest Procedure |
| <0.90 | Non-reactive (Negative) | HBsAg not detected | Retesting not required |
| ≥ 0.90 to < 1.0 | Borderline | Borderline zone (undetermined) | All initially reactive or borderline samples should be retested in duplicate. |
| ≥ 1.0 | Reactive (Positive) | HBsAg detected | |
| HBSAG - Repeat Testing | |||
|---|---|---|---|
| Initial Result | Result after retest | Final Result | Interpretation |
| Borderline | 2 of the 3 results have a COI <1.0 | Non-reactive | HBsAg not detected |
| 2 of the 3 results have a COI ≥ 1.0 | Reactive | Presumptive evidence of HBV. Test will be sent out for confirmation.* | |
| Reactive | 2 of the 3 results have a COI <1.0 | Non-reactive | HBsAg not detected |
| 2 of the 3 results have a COI ≥ 1.0 | Reactive | Presumptive evidence of HBV. Test will be sent out for confirmation.* | |
*Repeat values that are Reactive (>1) will reflex the mayo sendout HBAG for confirmation.
