Urine Protein Flashcards
It is less than ______ and is not
detectable by the usual methods in urinalysis
less than 10 mg/dl or 100 mg/24 hours
The presence of an increased amount of protein in the urine is termed
proteinuria
often the primary indicator of renal disease and its detection helps in the identification, treatment and prevention of renal disease
proteinuria
What are the tests to determine urine protein?
a. Heat and Acetic Acid Test:
b. Sulfosalicylic Acid Test
c. Robert’s Test
d. Heller’s Ring Test
Positive results are shown either in the form of ______ at the junction of the reagent
cloudiness or a ring
A test that is now being used in most clinical laboratories
Sulfosalicylic acid test
only done at room temperature
Sulfosalicylic acid
It employs the principle of protein error of indicators
Reagent strip
Ring or cloudiness is distinct and granular against light (0.2
to 0.5 gm

Ring or cloudiness is thick and dense against light, opaque
and may solidify (2 mg% and o

Ring or cloudiness is distinct against a black background
(0.05 to 0.2 gm
+1
Ring or cloudiness is just perceptible against a black
background (less than 0.05 gm%)

Ring or cloudiness is heavy against light with distinct
flocculi (0.5 to 2 mg

Routine urinary screening for sugars can be done using

Example of copper reduction test
(Benedict’s test, Fehling’s test, Clinitest) and reagent strip.
