| Test | Normal Value | Value | Result Date | Method / Lab |
|------|-------------|-------|-------------|--------------|
| Hepatitis B Surface Antigen | NEG | **NEG** | Mar 10, 2025 10:01 PM | CMIA on Abbott Alinity. Cedars-Sinai Med Ctr Dept of Pathology & Lab Medicine, 8700 Beverly Blvd, Los Angeles CA 90048. CLIA# 05D0541033. Director: Anders H. Berg, M.D.-Ph.D. |
| Hepatitis C Antibody | <0.80 S/CO | **0.10** | Mar 10, 2025 10:04 PM | CMIA on Abbott Alinity. Same lab. |
| HIV Ag/Ab Combo | NEG | **NEG** | Mar 10, 2025 10:04 PM | Same lab. |
| HTLV I/II Antibody | NEGATIVE | **NEGATIVE** | Mar 12, 2025 12:00 PM | Performed by ARUP Laboratories, 500 Chipeta Way, Salt Lake City, UT 84108. Director: Jonathan R. Genzen, MD, PhD. CLIA# 46D0523979. |
| Syphilis, T. Pallidum Interpretation | NONREACTIVE | **NONREACTIVE** | Mar 10, 2025 10:02 PM | Same Cedars-Sinai lab. |
### Hepatitis C Antibody — Interpretation Key
Results reported using signal-to-cutoff (S/CO) ratio:
- POSITIVE: ≥ 1.00
- INTERMEDIATE: 0.80 to 0.99
- NEGATIVE: 0.00 to 0.79
CDC recommends all S/CO ratios between 1.00 and 4.99 be confirmed with additional PCR testing.
### HTLV I/II — Notes
Based on the non-reactive anti-HTLV ELISA screen, the HTLV Western Blot is not indicated and therefore not performed.
This assay should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cell, Tissues and Cellular and Tissue-Based Products (HCT/P).
