AccuBase A1c
Test Kit
FDA approved for
over-the-counter (OTC) use
(No
Prescription required).
Patent
Pending Multi-Method Laboratory Analysis Procedure.
The
AccuBase A1c Test
uses a unique and highly specialized
multi-method laboratory analysis (HPLC-IE/BA)
to evaluate your A1c level. The two (2) step process includes a screening
step to detect hemoglobin variants
and/or
disturbed erythrocyte kinetics (DEK) by HPLC-Ion Exchange (IE). The second
step includes the use of an interference -free procedure HPLC-Boronate Affinity
(BA), that provides an A1c value free of possible
interferences including chemically modified derivatives.
This
multi-method approach provides the most comprehensive evaluation of
individual hematology surrounding A1c as the most
recent inference of glycemic control by any laboratory or method available
in the U.S.
A proper A1c
determination should always include the evaluation of the individuals Red
Blood Cells at the time of A1c measurement. The AccuBase A1c
multi-method analysis does this and more. Healthcare professional and patients
alike should remember to:
"Treat the
patient not just the A1c number"
Treating the
patient includes evaluating red blood cells and screening for any
possible hemoglobin variants.
Extremely
high or low A1c values should always be evaluated for the presence of
possible abnormal hemoglobins.
<4.0% or >15.0%
The AccuBase A1c
Test Kit is a highly accurate test (CV's < 1.0%) capable of
detecting abnormal and/or silent hemoglobin variants such as hemoglobin S,
and C and F and over 850 others. Each
sample is first screened for presence of abnormal hemoglobins and/or disturbed
erythrocyte kinetics (abnormal age or volume of red blood cells) Example; anemia
(which can falsely lower the A1c value).
Individuals with long-standing diabetes may present with a condition called
erythropoietin (EPO) deficiency. EPO deficiency and/or anemia
are
considered serious conditions requiring appropriate medical intervention. DEK can adversely affect the A1c answer and each sample should be screened for the presence of DEK.
Estimates
report that over 650,000
Black Americans with diabetes are know to have the Sickle Cell Trait
(Hb "S,
C or F")
"Don't be fooled by claims of accuracy when an A1c method and/or disposable monitoring device has CV's (coefficient of variation) greater
than 2.0% or can not detect an abnormal hemoglobin"
"An A1c method and/or monitoring device with a CV of
7.0 % could mean that if your actual A1c level was 6.5% it could be reported anywhere
from 5.0% to 8.0% providing false and/or misleading therapeutic
information," not to mention the impact of an abnormal hemoglobin on the A1c
value that the
particular method or device is incapable of detecting.
Each
AccuBase A1c sample
is analyzed by an HPLC-IE procedure with resulting printed Chromatogram as shown below.
Our laboratory staff is available to discuss individual chromatograms with
your physician and/or medical personnel.
The graph below (left)
demonstrates a normal chromatogram with no hemoglobin variants present and a normal A1c
level.
The Chromatogram to the
(right) demonstrates an highly elevated level of hemoglobin F (25.6%). This
elevated level of Hb F resulted in a sub-normal A1c value
of 3.2%. Normal range of A1c assay (4.2% - 6.0%).
Unless
you have been screened for hemoglobin variants you would not know you carry the hereditary
persistent variant, or
be aware of its associated impact on your A1c level.
