Whenever possible, the diagnosis of malaria should always be confirmed by laboratory tests. These should include:

* Laboratory workup

, , and and increases in lactic dehydrogenase may be marked with large P. falciparum parasite burdens.
Microcytosis may be seen in patients from malaria-endemic areas but is often due to iron deficiency or thalassemia.
Leukocyte counts may be high, normal, or low.
Platelet counts may be normal or slightly low but have been observed to be <70,000/μL in P. falciparum infection398 and occasion- ally in P. vivax infection.
Sodium may be slightly low, possibly owing to syndrome of inappropriate antidiuretic hormone, excessive vomiting, or urinary losses.
Acidemia (pH less than 7.35), acidosis (bicarbonate < 15 mmol/L), and lactate levels >5 mmol/L can be seen in severe P. falciparum malaria (see later).
Some degree of renal impairment is common in falciparum malaria and may be associated with increased creatinine, proteinuria, and hemoglobinuria.
Serum glucose is often low in children with falciparum malaria, but it is commonly normal in adults.
In children with severe falciparum malaria, bacteremia/sepsis may be present at the time of initial clinical evalua-tion and blood cultures may be positive.402,403
