MODULE 6 Flashcards
(24 cards)
tubular reabsorption of
glucose is below normal
RENAL GLUCOSORIA
Glucosuria is caused by:
- prerenal condition (hyperglycemia)
- renal condition (defective tubular absorption)
excessive thirstiness
POLYDIPSIA
excessive urination
POLYURIA
excessive eating of sweet food
POLYPHAGIA
blurring of vision
RETINOPATHY
where sugar is stored; hard to
eliminate when the patient consecutively and
excessively eats
❏ Hemoglobin A1c -
found at an early age; congenital
dysfunction of pancreas.
Juvenile Diabetes
Copper reduction tests are based on the ability of
glucose and other substances to reduce copper (Dextrose) in Urine
sulfate (CuSO4) to cuprous oxide (Cu2O) in the
presence of alkali and heat.
PRINCIPLE FOR BENEDICT’S TEST
This test will detect _____of glucose.
0.15% to 0.2%
❏PROVIDE CURPIC IONS
COPPER SULFATE
PROVIDE ALKALINE MEDIUM
Sodium carbonate
the presence of glucose the entire solution will be
filled with precipitate ranging in color from
yellowish to
green to orange to brick red or red orange.
Potassium iodide chromogen
MULTISTIX
- O-toluidine chromogen
CLINISTIX
- Aminopropyl-carbazole
CHEMSTRIP
– Orthotolidine
TESTAPE
This is a specific test for glucose based on the use of
the enzyme glucose oxidase, which is impregnated on
a dip strip.
Clinistix Reagent Strip Test
Diastix is a specific test for glucose based on the use
of glucose oxidase, which is impregnated on the
reagent strip.
Diastix Reagent Strip for Glucose (Multistix)
The principle of
glucose is the
double sequential
enzyme reaction.
Color of chromogen from negative state to positive
state:
Potassium Iodide -
- Green to Brown
Color of chromogen from negative state to positive
state:
Tetramethylbenzidine
Yellow to Green
CLINITEST REAGENT
anhydrous copper sulfate, sodium hydroxide, citric
acid, & sodium bicarbonate.
Promotes “effervescence”, gas formation/heat
production.
