Fetal maternal hemorrhage screen
Rosette test
  

The Fetal maternal screen is a qualitative test to detect fetal maternal hemorrhage in Rh negative females with Rh positive infants.

  
EDTA whole blood
  
  
4.0 mL
  
1. The sample must be drawn post-delivery for post-partum evaluations
2. Wait at least one hour after delivery to collect specimen

Labelling instructions:
 
Excellian sites:
Tube must be labeled with the patients first and last name and Excellian MRN, date and time of collection and phlebotomist’s A#

Non-Excellian sites:
Tube must be labeled with the patient's first and last name and date of birth, date and time of collection and phlebotomist’s initials.
  

Submit tube unspun

Rosetting technique

  

Rh(D) typing may be performed at an additional charge if no Rh typing is in the patient history.

FMHS test interpretation:

  • If negative, 1 dose (300 microliters) Rh Immune Globulin is indicated.
  • If positive, see separate Anatomic Pathology, Heme Path panel report for further testing results and dose indicated. A Kleihauer Stain (457/85460.0 ) will be automatically reflexed to quantitate the possible fetal maternal hemorrhage. The quantity of fetal cells present is used to calculate the appropriate dose of Rh Immune Globulin to administer.
  • If the Rh of the infant is unknown or the infant is a D variant, the fetal maternal screen is unable to accurately screen for the fetal-maternal hemorrhage. A Kleihauer Stain will be automatically reflexed to quantitate the possible fetal maternal hemorrhage. The quantity of fetal cells present is used to calculate the appropriate dose of Rh Immune Globulin to administer
