DCA Vantage- spectrophotometry
Hemoglobin A1c is proportional to the level of glucose in the blood over 2 to 3 monthe. Regular measurement of HbA1C can be used in the long-term clinical monitoringn of diabetic patients. Improvement of metabolic control is indicated by a lowering of HbA1C values.
Point of Care DCA Hemoglobin A1C testing is available in certain ambulatory health centers and clinics and is performed by authorized operators in those areas.
Reference ranges are available in the DCA Vantage - Hemoglobin A1C test procedure located on the POC website: https://www.pathology.med.umich.edu/point-of-care
Reference ranges may change over time. Please refer to the original patient report when evaluating results.
The DCA Vantage will measure values between 2.5%-14%. Report out of range patient results as less than (<) 2.5% or greater than (>) 14.0%.
Specimens with hemoglobin values less than 7 g/dL should be tested with a different method.
Fingerstick: wipe away the first drop and use second drop for testing. Avoid excessive squeezing or milking.
Venous: collect in lithium, sodium, or EDTA syringe/tube
Sample must be tested within 5 minutes after collection in glass capillary.
Reject any sample that has remained in the glass capillary for longer than five minutes prior to analysis.
