The A1C test is also called glycated hemoglobin, HbA1c, or hemoglobin A1C. A1C provides an indication of average blood glucose control for the past 2-3 months. Hemoglobin is part of the red blood cells and binds to glucose. The A1C complex is formed when the glucose in the blood binds irreversibly (glycates) to hemoglobin. The higher the glucose level in the blood, the more that binds to the hemoglobin. Therefore, A1C values are proportional to the amount of glucose in the blood. The A1C result is in percentage (%) units in the United States or mmol/mol units in other countries. A1C reflects the amount of the hemoglobin that is glycated. Hemoglobin remains glycated for the lifespan of the red blood cell, about 90-120 days. Therefore, the A1C test reflects an average blood glucose control for the past 2-3 months.

FAQs - About A1CNow+®
What are the advantages of the A1CNow+ test by Chek Diagnostics?
A1CNow+ is fast, easy, and accurate. It provides A1C results in 5 minutes which are 99% laboratory accurate*. These A1C tests are for use in a doctors office. Providing real-time results outside of the laboratory, A1CNow+ is a hand-held, portable monitor which allows A1C testing in every exam room. Real-time A1C results allow for timely decisions on therapy changes when needed. The product requires no maintenance. Office staff no longer have to prepare and refrigerate lab samples. Obtaining A1C results during the patient office visit eliminates follow-up phone calls to discuss results and possible therapeutic changes. Our A1CNow® System is CLIA waived and certified by the National Glycohemoglobin Standardization Program (NGSP).
* Study results with healthcare professionals showed that the accuracy of A1CNow+ with fingerstick samples was, on average, 99%. This means that, on average, a true 7.0% A1C could read approximately 6.9%A1C. An individual A1CNow+ result may differ by as much as -1.0% A1C to +0.8% A1C from the true result. This represents the 95% confidence limits of a Bland-Altman plot.
How does the A1CNow+ test work?
The single-use test provides quantitative results from a single drop of blood. Lance the finger for an adequate drop of blood. Touch the blood drop with the tip of the blood collector. Insert the blood collector into the open end of the sampler body and shake. Insert the cartridge into the A1CNow+ monitor. Deliver the sampler body into the cartridge. Your result will display after 5 minutes. Results are 99% laboratory accurate*.

What is the National Glycohemoglobin Standardization Program (NGSP)?
The NGSP standardizes glycated hemoglobin test results so that clinical laboratory results are comparable to those reported in the Diabetes Control and Complications Trial (DCCT) where relationships to mean blood glucose and risk for vascular complications have been established. A key component of the program is the Reference Laboratory Network. The network interacts with manufacturers of glycohemoglobin methods to assist them first in standardizing their methods and then in providing comparison data for certification of traceability to the DCCT.
What is the Clinical Laboratory Improvements Amendment (CLIA)?
Clinical Laboratory Improvements Amendment (CLIA) is an act of Congress that established quality standards for all laboratory testing to ensure the accuracy, reliability, and timeliness of patient test results regardless of where the test was performed. 
What does CLIA waived mean?
A CLIA waived test has been reviewed by the Food & Drug Administration (FDA) and Centers for Medicare and Medicaid Services (CMS). It is defined as simple laboratory examinations and procedures that are cleared by the FDA for home use; employ methodologies that are so simple and accurate as to render the likelihood of erroneous results negligible; or pose no reasonable risk of harm to the patient if the test is performed incorrectly.
