89) A traveler is being evaluated at a local hospital for gastrointestinal pain, fever, and diarrhea. The
patient has recently returned from a month-long visit to Southeast Asia. The patient has no

where they were visiting. If liver function test results were elevated and bilirubinuria was noted,
which of the following would be the next logical test to order?
a. ELISA test for the Hepatitis B Surface Antigen (HBsAg)
b. Recombinant Immunoblot Assay (RIBA) test for Hepatitis C

mother also revealed that the baby has suffered from thrush (Candida infections) since birth.

findings showed a small thymus, no tonsils or lymph nodes. Which of the following immune
deficiencies DOES the patient present?

Q

91) You are performing a manual antibody titer in a clinical laboratory. You have made serial
dilutions of a patient’s plasma sample and you are looking for anti-streptolysin O antibodies. The
first tube contains pure patient plasma. The second tube contains a 1:2 dilution of the first tube.
The third tube contains a 1:2 dilution of the second tube and so on. The patient’s antibodies no
longer give visible reaction in tube 5, indicating their titer is tube 4 (or the last tube where there
is a positive result). What is the concentration of antibodies in tube 4 compared to the
concentration in tube 1?
a. The concentration of antibodies in tube 4 is the same as the concentration of antibodies
in tube 1.
b. The concentration of antibodies in tube 4 is about 1/4 the concentration of antibodies in
tube 1.
c. The concentration of antibodies in tube 4 is 1/8 the concentration of antibodies in tube
1.
d. The concentration of antibodies in tube 4 is 4 times the concentration of antibodies in
tube 1.
