QA aspects for HbA1c measurements.
OBJECTIVE
To provide mechanisms for evaluating HbA(1c) results that meet the criteria for review by the 2002 NACB guidelines for reporting HbA(1c) values.


METHODS
Complete blood count (CBC) data and comparison of obtained HbA(1c) with a calculated HbA(1c) were used to assess the validity of HbA(1c) results meeting the NACB review criteria.


RESULTS
The use of CBC data and a calculated HbA(1c) were found to be useful in evaluating the validity of unusual HbA(1c) results.


CONCLUSIONS
The validity of high and low HbA(1c) results can be checked by the review of CBC data and comparing a calculated HbA(1c) against the measured value.
