CORRECT Answers
Fasting glucose Glucose level after 8 hours of fasting.
Specificity Identifies patients without the disease; 100% specificity means no false positives.
Sensitivity Identifies patients with the disease; 100% sensitivity means no false negatives.
Incidence Number of new cases of a disease during a specific time period in a specific
population.
Prevalence Number of existing cases of a disease in a specific time in a given population.
Correlation Statistical relationship between two variables (not causation).
Alcohol detection in urine 7-12 hours.
Marijuana detection in urine 2-7 days.
Benzodiazepines detection in urine 3 days.
Amphetamine detection in urine 48-72 hours.
Likely causes of decrease in BUN 5 Liver failure, acromegaly, malnutrition, impaired absorption, nephrotic syndrome,
SIADH.
Symptoms of elevated BUN-5 Lethargy, confusion, delirium, convulsions, uremia.
Basophils function Phagocytic; used to identify chronic inflammation and high blood histamine
concentrations.
