<strong>CAPILLARYS</strong> <strong>HEMOGLOBIN</strong>(E) - 2010/10<br />
• When an abnormal hemoglobin is detected, use other means of identification (e.g., globin chain electrophoresis), or consult or send sample to a<br />
specialized laboratory.<br />
IMPORTANT: It is also necessary to analyze the hematologic state, as complementary results.<br />
• The migration of a hemoglobin variant close to Hb A involves an underestimation of Hb A fraction and that of the variant and consequently, an<br />
overestimation of Hb A2 fraction. In order to quantify Hb A2 with precision, it is necessary to delete the separate integration of both variants and<br />
Hb A, and to quantify these fractions together.<br />
• Some homozygous "S" subjects receive a "Hydrea"® (hydroxyurea) treatment that can induce synthesis of foetal hemoglobin. With <strong>CAPILLARYS</strong><br />
<strong>HEMOGLOBIN</strong>(E) procedure, the mobility of the induced hemoglobin F is not different from the physiological hemoglobin F.<br />
• Due to the resolution and sensitivity limits of zone electrophoresis, it is possible that some hemoglobin variants may not be detected with this<br />
method.<br />
Troubleshooting<br />
Call SEBIA Technical Service of the supplier when the test fails to perform while the instruction for the preparation and storage of materials, and for<br />
the procedure were carefully followed.<br />
Kit reagent Safety Data Sheets and information on waste products elimination are available from the Technical Service of the supplier.<br />
PERFORMANCE DATA<br />
Results obtained using the <strong>CAPILLARYS</strong> <strong>HEMOGLOBIN</strong>(E) procedure with the <strong>CAPILLARYS</strong> 2 FLEX PIERCING system indicate a very good<br />
reproducibility for quantitative analysis with a mean CV % of about 0.9 % for each hemoglobin component. All electrophoregrams were also interpreted<br />
visually.<br />
Results presented below have been obtained using the standard parameters of the <strong>CAPILLARYS</strong> software (smoothing 0 and hemoglobin fractions<br />
automatic quantification with <strong>HEMOGLOBIN</strong>(E) analysis program).<br />
Reproducibility within run<br />
Six (6) different blood samples (normal bloods A and E, blood F with increased Hb A2, blood B with Hb S, blood C with increased Hb F and blood G<br />
with Hb F, S and C components) were run using the <strong>CAPILLARYS</strong> <strong>HEMOGLOBIN</strong>(E) procedure in 8 capillaries of 3 <strong>CAPILLARYS</strong> 2 FLEX PIERCING<br />
systems and with 3 lots of <strong>CAPILLARYS</strong> <strong>HEMOGLOBIN</strong>(E) kits.<br />
The mean, SD and CV (n = 8) were calculated for each hemoglobin component, each sample, each lot of kit and each system.<br />
The table shows the values for the 6 tested samples for each hemoglobin component calculated with the 3 lots of kit and the 3 <strong>CAPILLARYS</strong> 2 FLEX<br />
PIERCING systems.<br />
