Question 1
-
The DAT is most likely to be negative in ABO HDFN. It's possible that the washing done as part of the DAT
may break the bonds between anti-A (or anti-B) and the newborn's poorly developed A (or B) antigens.
For which of the following antibodies is the DAT most likely to be negative when testing a newborn for
possible HDFN?
Answer: A

Question 2
-
A positive spot test shows agglutination of horse erythrocytes when added to patient serum previously
absorbed with guinea pig kidney, but not when added to patient serum previously absorbed with beef
erythrocyte stroma. The test is generally simple, sensitive, and specific, but false negative are common in
young children with mononucleosis.
The most common rapid slide test (MONOSPOT©) for infectious mononucleosis employs:

Question 3
-
CAMP is the correct answer because the case is typical of Streptococcus agalactiae(Group B strep). The main
presumptive identification test is CAMP. Bile solubility is positive for Streptococcus pneumonia. Coagulase
would be positive for Staphylococcus aureus. PYR is positive for Streptococcus pyogenes (Group A strep)
which is ruled out by the resistance to bacitracin. MicrobiologySpinal fluid cultures on a 3-day-old infant revealed beta-hemolytic, Gram-positive cocci occurring in pairs and chains. The organism was catalase-negative and bile esculin-negative. Resistance to 0.04 U disk of bacitracin was noted. The other test necessary to identify this organism is a positive test by:
