Test Code: OBPAN2
Synonyms/Keywords
​Prenatal panel without Rubella test
Test Components
​Panel includes an CBC with automated differential, Blood typing (ABO and Rh factor), Antibody Screen, Syphilis IgG Antibody, and Hepatitis B Surface Antigen.

Collection Processing Instructions
​This panel is only for patients with a record of Rubella immunity.
This test requires three samples:
1.  6.0 mL whole blood – Pink Top Tube (PTT) used for ABO, Rh factor and Antibody Screen.
2.  3.0 mL whole blood – EDTA Lavender Top Tube (LTT) used for CBC with automated differential.  2 peripheral 
     blood smears are also required.
3.  3.0 mL serum – Red Top Tube (RTT) used for Syphilis Antibody IgG, Rubella Antibody and Hepatitis B Surface  
    Antigen.
 
Processing instructions:
-Samples collected in a (RTT) must be removed from the cells within one hour for storage or transport.
- Regional Centers: Hemogram to be performed at local site; other tests to be sent to Marshfield Campus
 
High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay (HAA). It is recommended that patients refrain from consuming any multivitamin or supplement containing biotin for at least 72 hours prior to collection of a blood sample.
