Overview
Kawasaki disease is diagnosed on clinical presentation, although the laboratory findings are non specific for the diagnosis of Kawasaki disease normocytic anemia, thrombocytosis, with platelets ≥ 450×103/μL (450 × 109/L) after first week of acute disease leucocytosis with white blood cell count ≥ 15,000/μL (15.0 × 109/L), elevated erythrocyte sedimentation rate, elevated liver enzyme levels, hypoalbuminemia with ≥ 3.0g/dL (30g/L), elevated C-reactive protein, hyponatremia and sterile pyuria can be noted on laboratory investigations.
Laboratory Findings
Although non specific for diagnosis but the following laboratory findings are noted in Kawasaki disease:[1][2]
- Complete blood count (CBC) may reveal:
- Normocytic anemia
- Normochromic anemia
- Thrombocytosis
- Platelets ≥ 450×103/μL (450 × 109/L) after first week
- Leucocytosis
- White blood cell count ≥ 15,000/μL (15.0 × 109/L)
- Elevated Erythrocyte sedimentation rate
- Elevated C-reactive protein
- Liver function tests may reveal:
- Elevated liver enzyme levels
- Hypoalbuminemia ≥ 3.0g/dL (30g/L)
- Hyponatremia
- Sterile pyuria
