Which term describes a false-positive or false-negative test result caused by interfering substances in the specimen?
Answer: Analytical error due to matrix interference
Matrix interference occurs when components of the specimen (e.g., bilirubin, lipids, hemoglobin) affect the analytical reaction.
What does 'thrombocytopenia' indicate?
Answer: Decreased platelet count below normal
Thrombocytopenia is a platelet count below the lower reference interval, increasing bleeding risk.
The term 'reagent blank' in spectrophotometry is used to:
Answer: Zero the instrument against reagents without specimen
A reagent blank contains all reagents but no sample, correcting for absorbance contributed by the reagents themselves.
In hematology, 'anisocytosis' describes:
Answer: Variation in red blood cell size
Anisocytosis refers to significant variation in the size of red blood cells, reflected by an elevated RDW.
What does the term 'proteinuria' mean?
Answer: Presence of protein in urine above normal amounts
Proteinuria is the abnormal excretion of protein in urine, often a sign of renal disease.
The laboratory term 'titer' most commonly refers to:
Answer: The concentration or strength of a solution or antibody level expressed as a dilution
Titer is the highest dilution of a serum or solution that still gives a detectable reaction, used to quantify antibodies.
What is the meaning of 'hematocrit' (Hct)?
Answer: The percentage of blood volume occupied by red blood cells
Hematocrit is the proportion of blood volume composed of red blood cells, expressed as a percentage.
