Lab Report Analysis — Mrs. Somwati, 70F
⚠️ Disclaimer: This is an educational interpretation of lab findings. Please follow up with the treating physician (Dr. Susheel Agarwal) for clinical decisions and treatment.
Summary of Abnormal Findings
| Test | Result | Reference | Status |
|---|---|---|---|
| TLC (WBC) | 17,650 | 4,000–11,000 /cumm | 🔴 HIGH |
| Neutrophils | 81% | 40–75% | 🔴 HIGH |
| Lymphocytes | 15% | 20–45% | 🟡 LOW |
| PCV/Haematocrit | 34.9% | 35–45% | 🟡 LOW |
| MCV | 99.4 fL | 76–98 fL | 🔴 HIGH |
| MCH | 35.0 pg | 27–31 pg | 🔴 HIGH |
| MCHC | 35.2 g/dL | 31–35 g/dL | 🔴 HIGH |
| Haemoglobin | 12.3 g% | 12–17 | Normal (borderline) |
| LFT (Bilirubin, SGOT, SGPT) | All within range | — | ✅ Normal |
Clinical Interpretation
1. 🔴 Significant Leukocytosis with Neutrophilia (WBC 17,650; Neutrophils 81%)
The WBC is markedly elevated — nearly 1.6× the upper limit of normal. The neutrophil predominance strongly suggests:
- Active bacterial infection or sepsis (most common cause) — respiratory tract infection (pneumonia), urinary tract infection, or another occult source should be actively ruled out
- Inflammatory or stress response (trauma, surgery, severe metabolic stress)
- Less commonly: steroid use, chronic myeloid leukemia (CML) if persistent
"Pathologic leukocytosis is an increased WBC count that occurs as a result of disease, usually in response to infection or tissue damage, and is most often neutrophilia." — Henry's Clinical Diagnosis and Management by Laboratory Methods
The dizziness and weakness are consistent with systemic infection/inflammation causing these CBC changes.
2. 🔴 Macrocytic Pattern (MCV 99.4, MCH 35.0 — both elevated)
MCV of 99.4 fL is above the normal upper limit. Combined with a borderline-low haemoglobin (12.3 g%) and low haematocrit (34.9%), this points to macrocytic anemia, most likely due to:
- Vitamin B12 (cobalamin) deficiency — especially important in a 70-year-old female (common in elderly due to reduced intrinsic factor, gastric atrophy)
- Folate deficiency — dietary insufficiency
- Hypothyroidism (should be checked)
- Liver disease (but LFTs are normal here, making this less likely)
"Vitamin B12 or folate deficiency may be suspected when a macrocytic anemia (MCV >100 fL) or pancytopenia is present. Vitamin B12 deficiency, but not folate deficiency, is associated with neurological manifestations." — Textbook of Family Medicine
Dizziness and weakness are classic symptoms of B12 deficiency, which also causes subacute combined degeneration of the spinal cord if untreated.
3. 🟡 Low PCV (34.9%) with Normal-Borderline Hb
The haematocrit is mildly low, consistent with mild anemia. The RBC count (3.91 million/µL) is at the lower end of normal, supporting a mildly reduced red cell mass.
4. ✅ Liver Function Tests — All Normal
Bilirubin (total 0.9, direct 0.5, indirect 0.4), SGOT (22.1), SGPT (18.8) are all within normal limits. This makes liver disease an unlikely cause of macrocytosis.
Most Likely Clinical Picture
This 70-year-old woman with dizziness and weakness most likely has:
- An active infection (bacterial — causing leukocytosis + neutrophilia) — needs urgent evaluation for source (urine culture, chest X-ray, blood culture)
- Vitamin B12 or folate deficiency (causing macrocytic anemia, fatigue, and possibly contributing to dizziness/neurological symptoms)
These two conditions can coexist.
Recommended Next Steps (for the treating physician)
- Serum Vitamin B12 and Folate levels (to confirm macrocytic etiology)
- Thyroid function tests (TSH) — hypothyroidism causes macrocytosis and weakness
- Urine routine/culture — to rule out UTI (common in elderly women with leukocytosis)
- Chest X-ray — to rule out pneumonia
- Peripheral blood smear — to look for hypersegmented neutrophils (B12/folate deficiency) or blast cells
- CRP / ESR — to assess inflammatory burden
- Blood culture if febrile
Red Flags — Seek Urgent Care If:
- Fever > 38.5°C
- Confusion or altered consciousness
- Severe breathlessness
- Chest pain or inability to walk
