Definition:
Normal biochemical values are the reference ranges of substances measured in blood, urine, or body fluids in healthy individuals. These values help clinicians assess normal physiology, diagnose diseases, monitor treatment, and evaluate organ function.

Common Normal Biochemical Values

Parameter	Normal Value
Blood Glucose (Fasting)	70–100 mg/Dl
Blood Glucose (Postprandial)	<140 mg/Dl
HbA1c	4–5.6%
Total Protein	6.0–8.0 g/Dl
Albumin	3.5–5.0 g/Dl
Globulin	2.0–3.5 g/dL
Blood Urea	15–40 mg/dL
Serum Creatinine	0.6–1.2 mg/dL
Uric Acid	3.5–7.0 mg/dL
Total Cholesterol	<200 mg/dL
Triglycerides	<150 mg/dL
HDL Cholesterol	>40 mg/dL (Male), >50 mg/dL (Female)
LDL Cholesterol	<100 mg/dL
Sodium (Na⁺)	135–145 mEq/L
Potassium (K⁺)	3.5–5.0 mEq/L
Chloride (Cl⁻)	98–106 mEq/L
Calcium	8.5–10.5 mg/dL
Phosphorus	2.5–4.5 mg/dL
Magnesium	1.5–2.5 mEq/L
Total Bilirubin	0.2–1.2 mg/dL
Direct Bilirubin	0–0.3 mg/dL
AST (SGOT)	5–40 U/L
ALT (SGPT)	5–45 U/L
Alkaline Phosphatase	40–125 U/L
Serum Amylase	30–110 U/L
Serum Lipase	10–140 U/L

Importance

·         Serves as a reference for laboratory interpretation.

·         Helps in early detection of diseases.

·         Assists in monitoring disease progression.

·         Evaluates response to treatment.

·         Provides information about metabolic and organ function status.
