Specimen collection Flashcards
aseptic technique
method use to prevent contamination from microorganisms
-prevent/risks that you’ll experience with infection
aerobic culture
living only in presence of oxygen
anaerobic culture
living only in absence of oxygen
culture & sensitivity
lab cultivation of micro-organisms in a body fluid or substance placed in a special growth medium, followed by ID of antibiotic agents that can kill pathenogenic microorganisms grown
clean-voided (midstream) urine specimen (clean catch)
sample of urine collected after beginning to urinate into the toilet, stopping the stream of urine, then urinating into a sterile collection cup
double-voided urine specimen
this refers to a urine specimen which is collected after first emptying the bladder and then waiting until another specimen can be collected. These double-voided urine specimens are more accurate for purposes of glucose testing (urinalysis). If you test a urine specimen that has been held in the bladder for an extended period of time, it will not accurately reflect the glucose content in the bloodstream. A freshly, double voided specimen is preferred.
urine culture
A urine culture is a test to find germs (such as bacteria) in the urine that can cause an infection. Urine in the bladder is normally sterile. This means it does not contain any bacteria or other organisms (such as fungi). But bacteria can enter the urethra and cause a urinary tract infection (UTI).
urine reagent test strip
a chemically treated band that, when dipped into a urine sample and color changes are observed, yields information about pH, specific gravity, leukocytes or leukocyte esterase, blood, ketones, bilirubin or urobilinogen, and glucose (varying with the type of test strip used)
timed urine specimen
At the beginning of the time period, empty your bladder and discard that urine. Note the time. Collect all urine voided for the specified period of time in the container provided. At the end of the time period, empty your bladder and ADD this urine to the container.
dysuria
painful and difficult urination
hematuria
blood in urine
urgency
immediate and strong “desire to void” that is not easily deferred
Wound culture
A wound culture is a diagnostic laboratory test in which microorganisms—such as bacteria or fungi from an infected wound, are grown in the laboratory on nutrient-enriched substance called media—then identified.
point of care testing
at or near the site or time of patient care, as in point-of-care testing
lancet
a sharp, pointed device used to make small incisions or punctures in the skin
