Here is a complete breakdown of all three lab reports for Mr. R. Varun, 17 years, Male:
Complete Blood Count (CBC / Hemogram) Analysis
| Parameter | Result | Normal Range | Status |
|---|---|---|---|
| WBC (Total) | 5,800 cells/cumm | 4,000 - 11,000 | ✅ Normal |
| RBC | 5.24 Mill/cmm | 4.0 - 6.0 | ✅ Normal |
| Hemoglobin | 14.6 g/dL | 13.0 - 18.0 (Male) | ✅ Normal |
| HCT | 44.8% | 40-54% | ✅ Normal |
| MCV | 85.5 fL | 82-98 fL | ✅ Normal |
| MCH | 27.8 pg | 27-32 pg | ✅ Normal |
| MCHC | 32.5 g/dL | 32-36 g/dL | ✅ Normal |
| Neutrophils | 57% | 40-75% | ✅ Normal |
| Lymphocytes | 36% | 20-40% | ✅ Normal |
| Monocytes | 5% | 2-10% | ✅ Normal |
| Eosinophils | 2% | 1-6% | ✅ Normal |
| Basophils | 0% | 0-1% | ✅ Normal |
| Platelet Count | 1.28 Lakhs/cmm (128,000) | 1.5 - 4.5 Lakhs | ⚠️ LOW |
⚠️ Key Abnormal Finding: Low Platelet Count (Thrombocytopenia)
The platelet count of 1.28 Lakhs (128,000/μL) is below the lower limit of normal (1.5 Lakhs / 150,000). This is mild thrombocytopenia. The automated analyzer also flagged several platelet-related indices (MPV, PCT, P_LCR, P_LCC, PDW_SD, PDW_CV) as low, which is consistent with this finding.
Widal Test (Typhoid) - REACTIVE
| Test | Result | Significance |
|---|---|---|
| Salmonella Typhi 'O' | 1:160 | Elevated - significant |
| Salmonella Typhi 'H' | 1:80 | Borderline elevated |
| S. Para Typhi 'AH' | 1:20 | Within baseline |
| S. Para Typhi 'BH' | 1:20 | Within baseline |
The Widal test is REACTIVE. A titre of 1:160 for the 'O' antigen is diagnostically significant (titres ≥1:80-160 are considered positive in endemic areas). The 'O' antibody appearing at 1:160 strongly suggests active Salmonella typhi infection (Typhoid fever).
The low platelet count is directly linked to the typhoid infection - thrombocytopenia is a well-recognized complication of typhoid fever, caused by bone marrow suppression and immune-mediated platelet destruction during the infection.
Malaria Test
Both Plasmodium falciparum and Plasmodium vivax are NON-REACTIVE - no malaria detected.
Summary
Most values are normal. The main concerns are:
-
Typhoid fever (Widal positive) - The 1:160 'O' titre strongly suggests active typhoid. However, note that the Widal test has moderate sensitivity/specificity and can give false positives in malaria, typhus, and other conditions - as stated in Park's Textbook of Preventive & Social Medicine. A blood culture would be the gold standard to confirm.
-
Low platelets (128,000) - Mildly low, likely a consequence of the typhoid infection itself. Platelet counts typically recover with treatment of the underlying infection.
Important: Please consult a doctor immediately. If this is indeed typhoid, it requires antibiotic treatment (commonly ciprofloxacin, azithromycin, or ceftriaxone depending on local resistance patterns). The platelet count should be monitored during treatment. Do not self-medicate.
