type of urine for screening tests and qualitative urinalysis
random urine
type of urine ideal for cytology (ONLY if with prior hydration and exercise 5 mins before collection)
random urine
type of urine that is ideal specimen for routine screening or urinalysis and pregnancy testing (hCG)
first morning
type of urine used for evaluation of orthostatic proteinuria
first morning urine
type of urine used for glucose determination
second morning
urine for diabetic screening or monitoring
2 hour post prandial
urine preferred for testing glucose
2 hour post prandial
urine for routine screening and bacterial culture
midstream clean catch
urine for bacterial culture
catheterized urine
urine for anaerobic bacterial culture and urine cytology
suprapubic urine
urine for prostatic infection
three glass technique
in three glass technique, if the number of WBC and bacteria in the 3rd container is 10x greater than that of the 1st container it is indicative of
prostatitis
in three glass technique, it is used as the CONTROL for bladder and kidney function
2nd specimen
in Stamey-Mears test for prostatitis, this specimen is tested for urinary bladder infection
midstream urine (VB2)
timed specimen used for ADDIS COUNT
12 hour urine
timed specimen used for NITRITE DETERMINATION
4 hour urine
timed specimen used for UROBILINOGEN
afternoon urine
process of providing documentation of proper sample id from the time of collection to the receipt of lab results
chain of custody
required urine volume for drug specimen collection
30-45 mL
container capacity for drug specimen collection
60 mL
temperature of urine for drug testing
32.5-37.7 deg c
to prevent specimen adulteration
blueing agent
urine after collection must be delivered and tested within
2 hours 30 mins ideally
physical and chemical and microscopic characteristics of urine begin to change ___
as soon as the urine is voided
these are increased in unpreserved urine
pH
bacteria
odor
nitrite
decreased in unpreserved urine
clarity
glucose
ketones
conjugated bilirubin due to photo oxidation
urobilinogen
rbcs, wbcs, and casts
trichomonas
these disintegrate in dilute alkaline urine
rbcs, wbcs, casts
preservative of choice for routine UA and urine culture
refrigeration
preserves glucose and sediments well
thymol
preserves protein , does not interfere with routine analyses
boric acid
