Blood gases; electrolytes, anion gap, creatinine - plasma, urea - plasma. See also Alkalosis.
Defined as acidosis with a negative base excess and decreased bicarbonate.
Increased anion gap
Hydroxybutyrate is the preferred test, rather than acetoacetate.
Unexplained acidosis in childhood
See Organic acidaemias.
Serum and urine assays, as appropriate.
Methanol (see under Alcohols).
Glycol, oxalate – urine.
Normal anion gap
Intestinal bicarbonate loss, especially
In primary respiratory alkalosis.
Defined as acidosis with an increased pCO2.
Respiratory failure (acute/chronic)
In primary metabolic Alkalosis.
