phenylalanine
it is an essential amino acid found in milk, eggs, and other foods
ischemia
decreased blood flow to a body part or organ caused by constriction or plugging of the supplying artery
enzymatic reaction
chemical reaction controlled by an enzyme
polymorphonuclear white blood cells
white blood cells, leukocytes that have segmented nuclei
Glycosuria
presence of glucose in the urine
mononuclear white blood cells
white blood cells; leukocytes that have unsegmented nuclei
reractile
causing light to refract, creating a sharp boundary or image
renal threshold
level above which a substance cannot be reabsorbed by the renal tubules and therefore is excreted in the urine
filtrate
fluid that remains after a liquid is passed through a membrane filter
urinometer
a sealed glass float with a calibrated paper scale in its stem. with a slight spinning motion, it is placed in a cylinder containing a urine sample, and the value is read at the meniscus of the urine
reagent strip
strips used to test the specific gravity of urine
refractometer
device that measures the refraction of light through solids in a liquid
clinitest
glucose test on a reagent strip. a tablet is dropped into a test tube of urine, and the color of the tube’s contents is compared with chart
acetest
reagent tablets used to test for fat metabolism by-products
HCG
Substance detected in a positive pregnancy test
LH
increases in the concentration of urine shortly before ovulation
crystals
shape of urates or phosphates that settle out of refrigerated urine samples
Culture and sensitivity
procedure performed in the microbiology lab in which a specimen is cultured on artificial media to detect bacterial or fungal growth, followed by appropriate screening for antibiotic sensitivity
Bilirubinuria
medical term for a urine sample with a persistent greenish yellow foam that may indicate the patient has viral hepatitis
gold standard
definitive diagnostic test to which all others are compared
casts
protein that has taken on the size and shape of the renal tubules that is washed into the urine
cystoscopy
a visual examination of the urinary bladder using a fiberoptic instrument
colon-forming units
a term used when reporting bacteruria; one unit represents one bacterium present in the urine sample
metabolite
the product of drug metabolism that excreted into the urine
crenate
notches or leaflike, scalloped edges that form on an object, such as the changes that occur on the surface of a red blood cell when it is exposed to a hypertonic saline solution
supravite
a substance that is capable of staining living cells after their removal from a living or recently dead organism
