What is it indicated for?

The AxSYM" Homocysteine assay is a Fluorescence Polarization Immunoassay

(FPIA) for the quantitative measurement of total L-homocysteine in human serum

or plasma on the AXSYM System. Homocysteine values can assist in the

diagnosis and treatment of patients suspected of having hyperhomocysteinemia

and homocystinuria.

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