HOW ????

Identification of glycosuria

determination whether glycosuria is associated or not with hyperglycemia

Laboratory investigation aiming to differentiate the different causes of

glucosuria

Identification of glycosuria

Glucose

Oxidase

Test

This is done useing commercial, plasticcoated reagent strips

Patient preparation Explain

Check for drug history False negative

Equipment

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

Result Normal Findings

Abnormal

findings

No red coloure of stripeNo 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

determination whether glycosuria is associated or not with hyperglycemia

Fasting plasma glucose

2-hour postprandial blood sugar

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.

Result

normal range 70 mg/dL to 99 mg/dL

prediabetes

diabetes

100 mg/dL to126 mg/dL

above 126 mg/dL

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

2-hour postprandial blood sugar

2-hour

Reference

ranges

Less than 140

not use just one test result to diagnose the condition.

normal range

diabetes 200 and above
