AMT (MLS) EXAM QUESTIONS AND
ANSWERS 100% VERIFIED.
What tests are performed on donor units to find granulocyte
concentrations?
ABO & Rh, RBC antibodies, and infectious disease markers.
Which of the test(s) would you employ to examine a CSF for syphilis?
VDRL
Why can Sul hemoglobin not be detected by routine hemoglobin methods?
Sul hemoglobin cannot combine with oxygen and is not readily converted to
hemoglobin cyanide, which is required for detection using this method.
If a patient previously demonstrated ABs against certain antigens on a
screen in blood bank, but the pt has not needed blood in a long time(e.g.,
2 years). The pt returns and needs blood, but on their up-to-date screen
they are not reactive for those 2 antigens. Should you still give them
antigen specific negative blood when crossmatching?
Yes, historical clinically significant unexpected antibodies cannot be ignored.
Cyclosporine and tacrolimus (both immunosuppressive drugs) have
multiple therapeutic ranges, why?
Because both drugs have ranges dependent on the organ transplanted and
the time after transplantation.
Which WBC is found in the largest numbers in the peripheral blood of a
normal adult?
Segmented neutrophils.
Elevation in conjugated bilirubin is most likely to be found in what
condition?
Biliary obstruction.
,What is the purpose of allowing a prepared KOH mount to sit for 30
minutes?
To dissolve the background keratin and reveal fungal elements.
Which class of AB can agglutinate RBCs after AGH (anti-human globulin)
is added to the test tube?
IgA
What does this equation TN/TN+FP, measure?
Specificity
What action describes the major property of antidiuretic hormone?
Changes distal tubule water permeability.
How does ion concentration in the urine relate to specific gravity?
Specific gravity increases as ionic concentration increases.
The nephron includes:
The glomerulus, loop of henle, and the proximal convoluted tubule.
T/F: Isopropyl alcohol is a sensitizer?
False, it is a flammable.
The modified acid-fast stain is primarily used to identify:
Cryptosporidium oocysts
What terms refers to a deficiency of RBCs or hemoglobin?
Anemia
Transferrin usually shows a __________ during an acute phase response.
Decrease
Which tumor marker is used for colorectal cancer?
CEA
, Which autoimmune disorder is characterized by a homogenous pattern in
an immunofluorescence (IF) microscopy test for anti-nuclear antibodies
(ANAs)?
Systemic Lupus Erythematosus (SLE)
Semen for analysis should generally be received in the lab within:
One hour
Cortisol levels are higher in the:
Morning
The small club-shaped "drumstick" nuclear appendage attached to one
lobe of a neutrophil may be found in:
A normal female
If a patient has 3 inactive alpha-globin genes, which of the four alpha (a)
thalassemia classifications would they have?
Hb H disease
Which medication is known to cause Reye's Syndrome in children?
Acetylsalicylic acid
What would you expect the serum iron and TIBC to be in a person with
hereditary hemochromatosis?
Increased serum iron and decreased TIBC.
What is a common difference between paroxysmal cold hemoglobinuria
(PCH) and cold hemagglutinin disease (CHD)?
PCH is caused by an IgG AB while CHD is usually caused by an IgM AB.
Which test could be used to determine whether an abnormal PT and PTT is
caused by a factor deficiency or an inhibitor?
Mixing studies
Bleeding time is an in vivo measurement of:
platelet function and aggregation.
