Nutrition

Objective:

ICD-10:

Description:

Activities of blood transaminases, either aspartate (GOT) or alanine (GPT) aminotransferase, can serve as indications of a patient's vitamin B6 nutritional status.

This represents the functional availability of erythrocyte vitamin B6 in its coenzyme form. Its value increases with vitamin B6 deficiency.
