The Quantase Total Galactose Screening Assay is an enzymatic colorimetiic o -point method for the determination of total D(+)galactose (D(+)galactose + galactose-1-phosphate) in dried blood spot specimens taken from newborn human infants as part of a newbom screening programme.
The test is intended as a screening method for measuring the total D(+)galactose concentrations in newborn blood spot specimens. Elevated results are not diagnostic per se of galactosaemia, but indicate the urgent need for further study of the newborn from which the presumptive positive specimen was received.
The kit is NOT intended for use in monitoring the circulating concentrations of total D(+)galactose in galactosaemic patients nor to detect ante-natal galactosaemia.
Indications for use read by OCR from a scanned FDA 510(k) statement, so letters may be misread. Check the PDF before quoting it.
