- Comprehensive result is compared to FBS and Fasting Urine
2 hours post prandial urine specimen

identify:
the organic compound in the urine consists of (?), (?)
- creatinine
- urea (most abundant)
identify
he published a book for uroscopy
hippocrates
types of specimen
- Collected together with blood GTT
- Number of spx to be collected depends on the number of GTT’s (also tested for ketones)
glucose tolerance urine specimen
identify:
the waste material in the urine consists of (?), (?)
organic and inorganic compound
types of specimen
- For routine and qualitative UA
- Not reliable due to its diurnal variation, physical activity, and dietary intake
random/occasional/single
identify:
1st book published to use the color chart
fasciculus medicinae
identify:
he published a book about the charlatans (pisse prophets)
thomas bryant/brian
identify:

urobilin
identify:
urine is composed of 95% (?), and 5% (?)
- water
- formed elements
identify
the ultrafiltrate of the plasma
urine
identify:
the year when urinalysis becomes a routine test
1827 (richard bright)
identify
it uses reagent strip for chemical testing
dipstick urinalysis
identify:
the year when urinalysis was excluded as a routine test due to its complexity
1930
identify:
factors affecting the composition of urine
- dietary intake
- physical activity
- posture
- metabolism
- endocrine system
identify:
who invented the addis count?
thomas addis
identify:
they are uncertified (frauds), that lowers the credibility of urinalysis
pisse prophets (1600)
identify:

common urine preservatives
- no UA interference

- Use 1drop/ounce of specimen
phenol
identify:
how many colors are their in the color chart?
20
common urine preservatives
