Obstetric Panel with Fourth Generation HIV, Hepatitis C Antibody with Reflex

Also known as: OB Panel with HIV HCV, Prenatal Panel with HIV HCV

Use

This obstetric screening panel is intended to provide comprehensive prenatal infectious disease assessment by combining components commonly included in first-trimester screening, including hematologic evaluation (CBC with differential and platelets), antibody screen with reflex to identification, ABO Group and Rh Type, syphilis screening via RPR with reflex to titer and confirmatory testing, hepatitis B surface antigen with reflex confirmation, and now includes fourth-generation HIV antigen/antibody testing and hepatitis C antibody with reflex testing. It supports maternal and fetal health management by facilitating timely identification of infectious risks during pregnancy.

Special Instructions

Specimen requirements include multiple tubes: whole blood in EDTA (lavender-top), whole blood in ACD (yellow-top), and serum. Collection instructions note that the EDTA tube must be collected last, maintained at room temperature, not refrigerated, spun, and kept unopened, with labeling specific to HIV testing. Separate assay-level methodologies and stability criteria apply to each component of the panel.

Limitations

Limitations are determined at the individual assay level (e.g., CBC, antibody screen, RPR reflex, hepatitis B Ag reflex, HIV fourth generation, HCV antibody). Specific limitations are not detailed in the available summary; users should refer to the individual assay information for capture of limitations such as window periods, potential false-reactivity or sensitivity constraints.
