Testing for Metabolic Acidosis

Biomarker Patterns

Assessment of specific biomarkers and the anion gap can help evaluate metabolic acidosis. These include:



Persistent metabolic acidosis should involve a workup for inborn errors of metabolism and include evaluation of ketosis, hypoglycemia, lactatemia, organic acidemia, and mitochondrial dysfunction (Guerrero 2018).

Low-grade metabolic acidosis can occur when the body retains acid and depletes bicarbonate stores, which can be damaging to tissues and organs if prolonged. Diet is a significant factor in low-grade metabolic acidosis and should be evaluated and addressed when the body’s acid-base balance is out of balance (DiNicolantonio 2021). Diet modifications can help reduce the acid load and help alkalize the urine.

New call-to-action
