In short

O-Phosphoethanolamine is a small phosphorus-containing molecule, not a protein building block. It is an intermediate in the metabolism of phospholipids, the fats that make up cell membranes. It appears in plasma in small amounts.

Comprehensive Health Check

Reviewed against DGKL reference practice.

Why test this?

O-Phosphoethanolamine is reported as part of a full amino acid profile, mainly as a clue rather than a routine health marker. A markedly raised level can point toward hypophosphatasia, an inherited bone enzyme disorder, so it is read in the context of the whole profile and other tests.

What is a normal result?

Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.

Adult reference values as used by Aniva. Ranges are guidance and can vary by laboratory and method.

Group	Normal range
Adults	Below 12 µmol/L

Your Aniva report reads your result against these values together with your age, sex and the rest of your panel.

Ranges are guidance and vary by lab and assay, aligned with DGKL practice. Always read your result against your own lab's reference interval.

What insights will this test give you?

Whether O-phosphoethanolamine sits in the usual low adult range.
Context for the other compounds reported in your profile.
In rare cases, a flag that supports a closer look at bone enzyme function.

What can affect this result?

What can skew the result

Results are affected by recent diet, recent protein intake, fasting state and the time of day the sample is taken.
