eosinophilia absolute eosinophil count 0.68 causes interpretation CBC
Here is a full interpretation of this haematology report for Mrs. Neetu Saxena, 52F, dated 21 May 2026.
Summary
Most values are within the normal range. There are three flags worth attention:
| Parameter | Value | Reference | Status |
|---|---|---|---|
| Eosinophils (%) | 8.9% | 1-6% | HIGH |
| Absolute Eosinophil Count (AEC) | 0.68 x10^3/uL | 0.02-0.5 | HIGH |
| MPV (Mean Platelet Volume) | 12.0 fL | 7-9 fL | HIGH |
| Absolute Basophil Count | 0.01 x10^3/uL | 0.02-0.10 | Marginally low (borderline) |
Parameter-by-Parameter Breakdown
White Cell Differential (%)
- Neutrophils - not explicitly listed as a % but the ANC of 3.76 is normal
- Lymphocytes 34.7% - normal (20-40%)
- Monocytes 7.1% - normal (2-10%)
- Eosinophils 8.9% - elevated (normal 1-6%)
- Basophils 0.1% - normal (0-2%)
Absolute Leucocyte Counts
- ANC 3.76 (normal 2.0-7.0) - no neutropenia or neutrophilia
- ALC 2.65 (normal 1.0-3.0) - normal
- Absolute Monocyte 0.54 (normal 0.20-1.00) - normal
- AEC 0.68 (normal 0.02-0.5) - mild eosinophilia
- Absolute Basophil 0.01 (normal 0.02-0.10) - marginally below range, not clinically significant on its own
Platelets
- PLT 205 (normal 150-410) - normal
- MPV 12.0 fL (normal 7-9 fL) - elevated
Clinical Significance of Abnormal Values
1. Mild Eosinophilia (AEC 0.68 x10^3/uL)
This is classified as mild eosinophilia (500-1500 cells/uL). The most common causes in a 52-year-old woman in India are:
- Allergic conditions - allergic rhinitis, asthma, atopic dermatitis (most common)
- Parasitic infections - especially helminths (roundworm, hookworm, filaria) - a key consideration in India
- Drug reactions - any recent medication use should be reviewed
- Skin diseases - eczema, urticaria
- Less commonly - early EGPA (Eosinophilic Granulomatosis with Polyangiitis), eosinophilic esophagitis, or inflammatory bowel disease
At this level (0.68), serious causes like hypereosinophilic syndrome (which needs >1.5 x10^3/uL for 6+ months) are unlikely.
Action recommended: Review for symptoms of allergy, asthma, skin conditions, or recent medications. Stool examination for ova and parasites is a low-cost, high-yield first step given the geographic context.
2. Elevated MPV (12.0 fL)
MPV reflects platelet size and is a marker of platelet activation and production. An elevated MPV with a normal platelet count (205) can be seen in:
- Thyroid disorders (hypothyroidism is common in middle-aged women)
- Metabolic syndrome / diabetes / cardiovascular risk
- Inflammatory conditions
- Vitamin B12 or iron deficiency (though these more typically affect RBC indices)
- Increased platelet turnover from any cause
Action recommended: Thyroid function tests (TSH, T3, T4) and fasting blood glucose/HbA1c would be a reasonable next step, especially given her age and gender.
What Is Normal in This Report
- No anaemia suggested (haemoglobin not shown on this page, likely on an earlier page of the 16-page report)
- Platelet count is normal - no thrombocytopenia or thrombocytosis
- No neutrophilia or neutropenia - no active bacterial infection pattern
- No lymphocytosis - no viral infection or lymphoproliferative pattern
- No monocytosis
Key Takeaways
- Mild eosinophilia is the primary finding - most likely allergic or parasitic in origin given the context. No urgent workup needed, but stool exam + allergy history is warranted.
- Elevated MPV is a soft marker - check thyroid function and metabolic panel.
- Platelet count and all other absolute counts are normal - no haematological emergency.
- This is page 13 of 16 - the full report includes RBC indices, haemoglobin, and other parameters that would complete the picture.
This report does not suggest any malignancy, serious infection, or acute haematological disorder based on the visible parameters.
