LOINC long common name : PhenX - fasting plasma glucose for diabetes screening - blood draw protocol 140801;
LOINC short name : Fast plasma gluc blood draw proto;
LOINC description : Participants are asked to fast for at least 9 hours (generally overnight) prior to
the Fasting Plasma Glucose test. Participants are asked a series of exclusionary questions
and then have blood drawn. The plasma is separated from the blood via centrifugation
and glucose concentration is determined via a hexokinase-mediated reaction. If the
9-hour fast is not met, the Diabetes Working Group recommends that the test can still
be completed as a casual glucose concentration (see the protocol for casual glucose
reference ranges for screening plus/minus Diabetes). The Diabetes Working Group refers
users to the Fasting Plasma Proinsulin assay in Diabetes Supplemental Information
to obtain more information about insulin resistance.;
