CLINICAL IMMUNOLOGY AND SEROLOGY
FINAL PAPER 2026 COMPLETE TEST BANK
QUESTIONS AND DETAILED ANSWERS
◉ congenital rubella syndrome. Answer: caused by infection during
pregnancy and can result in a wide spectrum of birth defects
in utero infection can also result in fetal death
fetus is most likely to develop anomalies if the mother becomes
infected during the first month of pregnancy
◉ rubella testing. Answer: because IgM antibodies disappear
quickly, their presence is indicative of a current or very recent
infection
because IgG antibodies appear early in the course of the disease and
persist, their presence does not necessarily indicate current or
recent infection
◉ rubella testing. Answer: because IgM does not cross the placental
barrier, demonstration of IgM antibodies in a neonate is diagnostic
of congenital rubella syndrome
, ◉ HAI (rubella testing). Answer: most widely used test for the
detection and quantitation of rubella antibodies
does not distinguish between IgG and IgM antibodies and is
therefore most useful as an indicator of immune status
a titer of <8 is considered to be indicative of a prior infection
◉ febrile diseases. Answer: group of microbial infections
characterized by fever and the production of antibodies known as
febrile agglutinations
Brucellosis
Paratyphoid fever
Rocky Mountain spotted fever
Tularemia
Q fever
◉ Q fever and rocky mountain spotted fever. Answer: caused by
rickettsiae
◉ tests for febrile diseases. Answer: Widal's test
