Understanding Your
Blood Test Reports
Decode every number. Know what your CBC, lipid profile, LFT, KFT, and HbA1c really mean — explained by experts at AGAM Diagnostics, Madurai.
Blood tests are among the most powerful, non-invasive tools in modern medicine. Yet many patients receive their reports and feel overwhelmed by unfamiliar terms, numbers, and reference ranges.
At AGAM Diagnostics, a NABL-accredited laboratory in Madurai, we believe knowledge empowers better health decisions. This comprehensive guide explains how to read your blood test reports with technical details, normal ranges, clinical significance, and answers the questions patients ask most.
How to Read Your Blood Test Report
Test Name / Parameter
What was measured
Your Result
Your actual value
Reference Range + Flag
Normal values + H/L flag
Pro Tip: Always compare your result to the reference range printed on your report, not generic values found online.
1. Complete Blood Count (CBC) – Your Body’s Cellular Health Snapshot
| Parameter | Typical Normal Range (Adults) | High May Indicate | Low May Indicate |
|---|---|---|---|
| Hemoglobin (Hb) | Men: 13.2–16.6 g/dL Women: 11.6–15.0 g/dL | Dehydration, polycythemia | Anemia |
| Hematocrit (Hct) | Men: 38.3–48.6% Women: 35.5–44.9% | Dehydration | Anemia, blood loss |
| WBC Count | 4,000–10,000/µL | Infection, inflammation | Bone marrow suppression |
| Platelets | 150,000–400,000/µL | Inflammation | Bleeding disorders |
2. Lipid Profile – Assessing Cardiovascular Risk
| Parameter | Desirable | Borderline | High Risk |
|---|---|---|---|
| Total Cholesterol | < 200 mg/dL | 200–239 | ≥ 240 |
| LDL Cholesterol | < 100 mg/dL | 100–129 | ≥ 130 |
| HDL Cholesterol | ≥ 60 mg/dL | 40–59 (men) | < 40 (men) |
| Triglycerides | < 150 mg/dL | 150–199 | ≥ 200 |
3. Liver Function Tests (LFTs)
ALT, AST, ALP, Bilirubin, Albumin – key markers of liver health and function.
4. Kidney Function Tests (KFT)
BUN, Creatinine, eGFR – evaluate filtration efficiency and detect early kidney disease.
5. Blood Glucose & HbA1c – Diabetes Monitoring
- Fasting Blood Glucose: 70–99 mg/dL (normal)
- HbA1c: <5.7% (normal), 5.7–6.4% (prediabetes), ≥6.5% (diabetes)
Factors That Affect Your Results
Age, sex, fasting status, medications, hydration, exercise, and lab methodology can all influence results.
When to Follow Up With Your Doctor
Critical flags, persistent abnormalities, or symptoms like fatigue, jaundice, swelling, or chest pain require prompt medical attention.
Frequently Asked Questions
What does it mean if my CBC shows low hemoglobin? ↓
Low hemoglobin usually indicates anemia. Common causes include iron deficiency, vitamin B12 or folate deficiency, chronic disease, or blood loss. Further tests are required.
My lipid profile shows high LDL. What next? ↓
Lifestyle changes and possibly statin therapy based on your cardiovascular risk. Consult your physician for personalized advice.
Why is my creatinine slightly elevated? ↓
It may be due to mild dehydration, medications, or early kidney changes. eGFR provides better context.
Do I need to fast for all blood tests? ↓
No. Only specific tests require fasting. Your lab slip will clearly indicate fasting requirements.
How often should I get routine blood tests? ↓
Healthy adults: once a year. People with risk factors or chronic conditions: every 3–6 months.
