Diagnosis: Iron Deficiency Anemia (IDA)
Based on this lab report for Poonam (32Y/F), the findings point clearly to Iron Deficiency Anemia, with secondary findings of reactive thrombocytosis and dyslipidemia.
Primary Diagnosis: Iron Deficiency Anemia
CBC findings supporting this:
| Parameter | Observed Value | Significance |
|---|
| Hemoglobin | 9 g/dL | Low (normal female: 12–16 g/dL) — anemia confirmed |
| Hematocrit (PCV) | 31.4% | Low (normal: 36–48%) |
| MCV | 77.3 fL | Low-normal, trending microcytic |
| MCH | 22.2 pg | Low — hypochromic |
| MCHC | 28.7 g/dL | Low — confirms hypochromia |
| RDW-CV | 18.8% | Elevated — hallmark of IDA |
| RDW-SD | 52.3 fL | Elevated — anisocytosis |
Iron studies confirming IDA:
| Parameter | Observed Value | Significance |
|---|
| Serum Iron | 26.63 µg/dL | Very low (normal: 50–150 µg/dL) |
| UIBC | 433.1 µg/dL | Elevated — indicates iron-hungry transferrin |
| Transferrin Saturation | 5.79% | Severely low (normal: 25–50%; IDA threshold: <20%) |
Per Harrison's Principles of Internal Medicine (p. 2886), transferrin saturation <20% is diagnostic of an iron-deficient state, and this patient's saturation of 5.79% is critically low.
Per Harrison's (p. 2889), the elevated RDW in the context of microcytic/hypochromic indices helps distinguish IDA from thalassemia — thalassemia typically shows a normal RDW with normal/elevated serum iron.
Secondary Finding: Reactive Thrombocytosis
- Platelet count: 492 × 10³/µL (normal: 150–400 × 10³/µL)
- Elevated platelets are a well-recognized reactive response to iron deficiency anemia, particularly in young women. This resolves with iron replacement.
Additional Abnormalities
Lipid panel:
- HDL Cholesterol: 35 mg/dL — Low (normal female: >50 mg/dL)
- HDL/LDL Ratio: 0.39 — Low, suggesting relative dyslipidemia/cardiovascular risk factor
Bilirubin (mildly elevated total: 1.43 mg/dL, indirect: 1.15 mg/dL): Could reflect mild hemolysis from iron deficiency-related red cell fragility, or simply a constitutional/Gilbert's pattern. Not alarming in isolation.
Renal and glucose: Creatinine 0.45 mg/dL is slightly low (common in young women with low muscle mass — not pathological). ABG 80 mg/dL is within normal fasting range.
Summary
Primary diagnosis: Iron Deficiency Anemia (IDA) — moderate severity (Hb 9 g/dL), microcytic-hypochromic, with severely depleted iron stores (transferrin saturation 5.79%). Reactive thrombocytosis is secondary to IDA. Low HDL warrants dietary/lifestyle attention.
Recommended next steps (for the treating physician):
- Oral iron supplementation (ferrous sulfate or ferrous ascorbate)
- Investigate the cause of IDA: dietary deficiency, menorrhagia, GI blood loss, malabsorption
- Repeat CBC and iron studies after 4–6 weeks of therapy
- Address low HDL with dietary modification
