, National Glycohemoglobin Standardization Program.
The correlation between the NGSP
and IFCC method is strong, but the IFCC method is more specific and precise because it measures only HbA1c and not other fractions of glycated Hb.
It is suggested that HbA1c should be reported in both NGSP
(%) and IFCC (mmol/mol) units9.
1c] must be done according to the DCCT method and in a laboratory accredited by the NGSP
The laboratory was awarded the CAP (College of American Pathologists) accreditation in May 2010 and is also NGSP
Level I Certified.
In FY99 and FY00, however, many labs in the United States, including several VHA facilities, were using methods not certified by the NGSP
Data on NGSP
, GDPPI, and SPOP were drawn from the Web sites of the Bureau of Economic Analysis, the Economic Report of the President, and the Bureau of the Census, respectively.
Physicians should make sure that their labs are NGSP
certified, that they participate in the College of American Pathologists Proficiency Program, and that they report results in terms of hemoglobin [A.
Glycosal now benefits from a CLIA waiver, signalling an additional approval from the Food and Drugs Administration, and a NGSP
certification, an independent quality assessment, both of which will greatly improve the attractiveness of the product in the American marketplace.
The test should be performed in a laboratory using a method that is NGSP
certified and standardized to the diabetes control and complication trial assay.
At the time of the original 4D study, this assay was not NGSP
certified, as NGSP
certification was not yet available (26).
was established by the American Association of Clinical Chemistry (AACC) to execute the protocol and establish the standardization process.
