What is it indicated for?

The Axis Homocysteine Enzyme Immunoassay is intended for the quantitative measurement of total L-homocysteine in human serum or plasma.

The device can assist in the diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocysteinuria.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
