Here is a complete interpretation of this CBC report for Mr. Sachin Shankar Patil, 25-year-old Male:
Overall Diagnosis: Macrocytic (Megaloblastic) Anemia
All the abnormal findings together point toward a single unifying diagnosis - most likely Vitamin B12 or Folate deficiency.
Abnormal Values - Explained
| Parameter | Result | Reference | Interpretation |
|---|
| Hemoglobin | 10.2 | 13.0-17.0 g/dL | Low - moderate anemia |
| RBC Count | 2.51 | 4.5-5.5 × 10¹²/L | Very low |
| PCV/HCT | 27.7% | 40-50% | Low - confirms anemia |
| MCV | 110.4 fL | 83-101 fL | High - macrocytosis |
| MCH | 40.8 pg | 27-32 pg | High - each RBC carries excess hemoglobin |
| Neutrophils | 37.1% | 40-75% | Mildly low |
| Lymphocytes | 52.9% | 20-40% | Elevated (relative lymphocytosis) |
| Basophils | 1.4% | 0-1.0% | Mildly elevated |
Normal Values:
- WBC Total (5440): Normal
- Monocytes (5.4%), Eosinophils (3.2%): Normal
- Platelet Count (215,000): Normal
- MCHC (36.9): Slightly above upper limit but not dramatically abnormal
What the Peripheral Smear Confirms
The pathologist's note is very telling:
- Anisopoikilocytosis+ - variation in RBC size and shape
- Predominantly normocytic normochromic but with macrocytosis+ and few macrovalocytes (oval macrocytes) - this is the hallmark smear finding in megaloblastic anemia
- Lymphocyte predominance in WBCs - consistent with relative lymphocytosis when neutrophils are suppressed
- Platelets adequate - not affected yet
Oval macrocytes (macro-ovalocytes) are the most specific peripheral smear finding for B12/folate deficiency megaloblastic anemia, as noted in Tietz Textbook of Laboratory Medicine.
What This Pattern Indicates
Primary Diagnosis: Megaloblastic Anemia
The combination of:
- Low Hb + Low RBC + Low HCT (anemia)
- High MCV (110.4 fL) - macrocytosis
- High MCH
- Oval macrocytes on smear
- Relative lymphocytosis + mild neutropenia
...is classic for megaloblastic anemia due to impaired DNA synthesis. In a 25-year-old male, the most common causes are:
- Vitamin B12 deficiency - most likely (dietary deficiency in vegetarians/vegans, pernicious anemia, malabsorption)
- Folate (Vitamin B9) deficiency - from poor diet, alcoholism, malabsorption, or increased demand
Recommended Next Steps
The pathologist correctly advised "Follow up CBC". The treating doctor should also order:
- Serum Vitamin B12 level (most important)
- Serum Folate / RBC Folate
- Peripheral smear review for hypersegmented neutrophils (another hallmark of megaloblastic anemia)
- Reticulocyte count
- If B12 deficiency confirmed: check for pernicious anemia (anti-intrinsic factor antibodies), dietary history
- LFTs and TSH to rule out liver disease and hypothyroidism as alternative causes of macrocytosis
Key Takeaway
This report strongly indicates moderate macrocytic anemia in a young man, almost certainly from Vitamin B12 or Folate deficiency. The RBC count of 2.51 (normal: 4.5-5.5) and hemoglobin of 10.2 (normal: 13-17) show the anemia is moderate-to-severe in terms of cell numbers. Prompt supplementation and investigation of the underlying cause is warranted.
