Why it matters

It links pituitary growth-hormone signaling, liver production, nutrition context, growth, body composition, and age.^[1,2]

What it affects

It can be a slower axis marker than a single growth hormone measurement.^[1,2]
It connects endocrine and liver domains.^[1,2]

Interpretation traps

Age, puberty, nutrition, liver disease, and assay method affect interpretation.^[1,2]
BioConst does not diagnose growth hormone disorders.^[1,2]
