ASCP MLS test with correct answers
A biomarker with a high specificity: - CORRECT ANSWERS-accurately detects the absence of
disease and has few false-positives
A biomarker with high sensitivity: - CORRECT ANSWERS-accurately identifies the presence of
disease and hos few false-negatives
A hapten is only antigenic when it is coupled with which of the following: - CORRECT
ANSWERS-Proteins
A mojor action of angiotensin II is: - CORRECT ANSWERS-increased vasocontriction
A patient experiences a mild allergic reaction to a transfusion, including urticaria, erythema (skin
redness), and itching. What is the most likely source of the allergen? - CORRECT ANSWERS-
Plasma proteins
Mild allergic reactions result from a patient's hypersensitivity to soluble allergens in the plasma
of the donor unit. The blood recipient forms antibodies to these allergens that are bound to IgE
on mast cells and cause the release of histamines. Allergen substances may be drugs or food
consumed by the blood donor.
Adiponectin: - CORRECT ANSWERS-Is aprotective cytokine. This cytokine is anti-inflammatory
and increases insulin sensitivity. Adiponectin is usually decreased in obesity
Alder-Reilly inclusions: - CORRECT ANSWERS-Mucopolysaccarids
Alpha thalassemia major: - CORRECT ANSWERS-
,Alpha thalassemia Major: - CORRECT ANSWERS-AKA as Hydrops Fetalis, is exhibited when
all four alpha chain gene loci are deleted or non-functional. The alpha chain is crucial to the
formation of hemoglobin variants that can conduct normal oxygen transport and gas exchange.
The genetic code --/-- is incompatible with life.
Amorphous phosphate crystals are found in: - CORRECT ANSWERS-Amorphous phosphate,
triple phosphate (ammonium magnesium phosphate), calcium phosphate, and ammonium urate
crystals are frequently found in alkaline urine specimens
Amorphous urates is found in: - CORRECT ANSWERS-Acidic pH urine
ANA - CORRECT ANSWERS-See 2 quiz #27
Approximately what percent of the overall population is Rh negative: - CORRECT ANSWERS-
15%
Average life span of platelets (in the body): - CORRECT ANSWERS-9.5 days
B lymphocytes and T lymphocytes are derived from: - CORRECT ANSWERS-Hematopoietic
stem cells

cell adhesion factor
CD5 antigen is normally found on which of the following lymphocyte populations? - CORRECT
ANSWERS-Mature T cells
Christmas Disease: - CORRECT ANSWERS-Deficiency in Factor IX
Chylomicrons are primarily composed of: - CORRECT ANSWERS-Triglycerides
Contact dermatitis is mediated by: - CORRECT ANSWERS-T lymphocytes
Coulometry: - CORRECT ANSWERS-An automated method for measuring chloride which
generates silver ions in the reaction
Crigler-Najjar syndrome: - CORRECT ANSWERS-Associated with increased levelss of bilirubin
in the blood as teh disorder affect the etabolism of bilirubin
Criteria for blood donation (Age, hematocrit, blood pressure, pulse and temperature): -
