bilirubinuria
presence of bilirubin in urine
COLONY-FORMING UNITS
term used when reporting bacteriuria; one CFU represents one bacterium present in the urine sample
CRENATE
Forming notches or leaflike scalloped edges on an object
culture and sensitivity (C&S)
procedure performed in microbiology lab, a specimen is cultured on an artificial media to detect bacterial or fungal growth.
CYSTOSCOPY
VISUAL EXAMINATION OF THE URINARY BLADDER, most reliable test for detecting bladder cancer
enzymatic reaction
chemical reaction controlled by enzymes
filtrate
fluid that remains after a liquid is passed through a membranous filter
GOLD STANDARD
THE PARAGON OF EXCELLENCE
metabolite
the metabolism of a substance such as a drug
mono-nuclear white blood cells
leukocytes with unsegmented nucleus
myoglobinuria
abnormal presence of hemoglobin-like chemical of muscle tissue in the urine; result of muscle deterioration
PHENYLALANINE
essential amino acid found in milk, eggs, and other foods
polymorphonuclear white blood cells
leukocytes with segmented nucleus. aka polymorphonuclear neutrophils.
refractile
causing light to refract or bend, creating a sharp boundary or image
renal threshold
level at which a substance cannot be reabsorbed by the renal tubules and are excreted in the urine
sediment
insoluble material that settles to the bottom of a urine specimen
supravital
of, relating to, or capable of staining living cells after their removal from a living or recently dead organism
routine urinalysis
-Most common laboratory examination used in the diagnosis and treatment of disease
Nephron
Functional unit of the kidney, filtration, reabsorbed, excretion
bowman’s capsule
The double-walled structure surrounding the glomerulus is the: ___________________
bowman’s space
Fluid filtered from the glomerular capillaries enters ___ ___, (the space between the two layers of the glomerular capsule),
urinary tract
2 kidneys, 2 ureters and 1 bladder
first morning specimen
Best option for routine screening, pregnancy tests, bacterial culture, or protein determination and microscopic examination. First morning urine will be the most concentrated.
24-hour urine specimen
testing of creatinine and hormones clearance rates
diabetes testing
need a second voided specimen
urine specimen
should be kept refrigerate and should be processed within 1 hour of collection
specimen cups
patients need to fill half way
Clean Catch Midstream Specimen
3 towellettes
urochrome
color depends on the concentration of the pigment
Cloudiness
may be caused by cells , bacteria , yeast, vaginal contaminants, or CRYSTALS; turbidity specimen
volume of urine daily
2 L
olglnuria
insufficient production of urine , which can be caused by dehydration
diabetes
fruity smell because of the presence of ketones
reagent
strip used to test specific gravity, does not have to be performed on a fresh specimen within 1 hour
Specific Gravity equipment
urinometer (not used at a physician’s office lab), a refractometer, or a chemical reagent strip
specific gravity
normal range from 1.005 to 1.030
urinometer
a sealed glass float with a calibrated paper scale in its stem
PH
range 5.5 to 8.0, urine PH is alkaline if the patient has bacteria
protienuria
first signs of renal disease
ketones
signs of diabetes mellitus, evaporates at room temp., should be tested immediately
hemoturia
presence of intact red blood cells in urine
bilirubinuria
signs of liver disease, store in dark place
urobiligen
normally presence in urine in small amounts
casts
may be caused by exercise, develop in renal tubules
nitrates
UTI ^nitrites ^leukocytes^ PH
substance present in all pregnancy tests
HCG
crystals
are present as a result of mediation or treatment, not reported, form when cooled,
clinitest
used to test glucosuria; gets really hot
Ovulation testing
test LH
toxicology
study of poisonous substances and their effects upon body parts
polyuria
increase urine output
leukocytes
infection
blood
presence of or onset of menstrual cycle, kidney stones, infection
how much urine is needed for a microscopic exam
10 ml
acetest
second test for ketones
Foam on a urine specimen
not reported
Quality control for the microscope
relies on standard commercial systems KOVA
squamous epithelial cell
most likely seen in a normal specimen
yeast looks like
red blood cells
Bacteria
tubular structure found in the urine and composed mainly of mucoprotein secreted by certain cells of the kidney
\”mousy\” smell
diagnosed with PKU phenlketonuria
