Test Name: Fructosamine – Serum

Clinical Significance:
Fructosamine is a glycated serum protein, mainly glycated albumin. The Fructosamine test reflects the mean plasma glucose concentration over the previous 2–3 weeks, making it a valuable tool for short-term glycemic monitoring. It is particularly useful in situations where HbA1c may be unreliable (e.g., hemoglobinopathies, hemolytic anemia, pregnancy, recent transfusions).

Reference Ranges (may vary by lab):

• Normal: 200 – 285 µmol/L

• Diabetes (poor control): >285 µmol/L

Indications:

• Monitoring short-term glycemic control

• Evaluation of therapy adjustments in diabetes

• Useful in conditions affecting HbA1c accuracy

• Gestational diabetes monitoring

Preparation:

• No fasting required.

• Blood sample taken at any time of the day.

Turnaround Time:

• Fast reporting – Results available within the same day (24 hours).

Test Name: RBS – Random Blood Sugar (Glucose Random)

Clinical Significance:
The Random Blood Sugar test measures glucose concentration in blood at a random time of the day, irrespective of the last meal. It is commonly used for screening and monitoring diabetes mellitus and for evaluation of patients with acute symptoms of hyperglycemia or hypoglycemia.

Reference Ranges (may vary by lab):

• Normal: 70 – 140 mg/dL (depending on last meal timing)

• Borderline: 141 – 199 mg/dL

• Diabetes: ≥200 mg/dL with classic symptoms of diabetes

Indications:

• Screening of undiagnosed diabetes

• Monitoring of known diabetic patients

• Evaluation of emergency cases with hyperglycemia or hypoglycemia

• Routine health check-up

Preparation:

• No fasting required.

• Sample can be taken at any time of the day.

• Same day reports
