3. HOW ????
Identification of glycosuria
determination whether glycosuria is
associated or not with hyperglycemia
Laboratory investigation aiming to
differentiate the different causes of
glucosuria

4. Identification of glycosuria
Glucose
Oxidase
Test
This is done useing commercial,
plasticcoated reagent strips

6. Patient
preparation Explain
Check for drug history False negative
Equipment

7. Procedure
Collect aspecimen after 30 to 45
minutes of drinking water
Precautions
not to
contaminate
test strip
container tightly
closed
Store it in a
cool place
Don't use
discolored

8. Result Normal Findings
Abnormal
findings
No red coloure of
stripe
No glucose is
present in urine
Red-colored
product
Glycosuria is
present as in
diabetes mellitus,
and other causes
Interfering
factors
contamination of the
specimen
failure to keep the
reagent strip
container tightly
Use of reagent strips
after the expiration
date
Presence of reducing
substances

10. determination whether glycosuria is
associated or not with hyperglycemia
Fasting plasma
glucose
2-hour
postprandial
blood sugar

11. fasting plasma glucose (FPG) test
if one’s body cannot generate enough insulin
or cannot appropriately respond to insulin,
fasting blood sugar levels will stay high.

12. Result
normal range 70 mg/dL to 99 mg/dL
prediabetes
diabetes
100 mg/dL to126 mg/dL
above 126 mg/dL

13. Interfering
factors
• In afternoon rather than in the morning.
• much time passes between when the blood is drawn
and the lab processes the sample
personal habits
two abnormal results from tests taken on two different days are required to
confirm a diagnosis.
previous or current medical conditions

14. 2-hour postprandial blood
sugar
2-hour

15. Reference
ranges
Less than 140
not use just one test result
to diagnose the condition.
normal range
diabetes 200 and above
