Overview
The diagnosis of malaria should be complemented by laboratory tests, which may reveal: anemia with decreased hemoglobin, hematocrit, haptoglobin and microctosis; and leukocyte count, which may be elevated or decreased. Biochemistry may reveal hypoglycemia, elevated creatinine and LDH; acidosis expressed by an elevated lactate level and decreased bicarbonate level; and mild hyponatremia due to vomiting and diarrhea. There may be present some renal impairment, which will be expressed by proteinuria and hemoglobinuria.
Laboratory Findings
Whenever possible, the diagnosis of malaria should always be confirmed by laboratory tests.
The table below displays the nonspecific laboratory abnormalities associated with malaria:[1][2]
| Test | Findings |
|---|---|
| Complete Blood Count | Decreased Hemoglobin Decreased Hematocrit Microcytosis Decreased Haptoglobin |
| White blood cell count | Elevated or Decreased Leukocyte Count |
| Biochemistry | Hypoglycemia Elevated Creatinine Elevated LDH Possible Hyponatremia Acidosis: High Lactate; Low Bicarbonate |
| Coagulation | Thrombocytopenia |
| Urinalysis | Proteinuria Hemoglobinuria |
