Abstract:
Introduction:Hemoglobin A1c (HbA1c) is fundamental in the diagnosis
and longitudinal monitoring of diabetes mellitus. Appropriate utilization is essential to ensure optimal glycemic
control, cost-effectiveness, and laboratory efficiency.
Regular audits are crucial for assessing adherence to testing
intervals and for identifying gaps in diabetes management.
The aim was to evaluate the utilization pattern and glycemic
outcomes of HbA1c testing at Hospital Teluk Intan in 2025.
Methodology:A retrospective descriptive audit was conducted using
Laboratory Information System data from 1 January to 31
December 2025. All HbA1c tests performed during the study
period were included. Rejected samples and duplicate tests
within 3 months for the same patient were excluded. Data
were analyzed for test volume, inpatient versus outpatient
distribution, age group, and glycemic control categories.
Results:A total of 10,208 HbA1c tests were performed, with 987
(9.7%) rejected samples. Among valid requests, 3,561
(34.9%) were inpatient and 5,660 (55.4%) were outpatient.
Adults accounted for 9,196 tests (90.1%), while paediatric
requests were minimal (n = 25). Regarding glycemic status, 4,502 (44.1%) had HbA1c <6.5%,
and 828 (8.1%) were between 6.5 and 7.0%. Suboptimal
control (7.0–10.0%) was observed in 2,443 patients (23.9%),
while 1,448 (14.2%) demonstrated poor control (>10.0%).
Overall, 38.1% of patients had HbA1c ≥7.0%, indicating
inadequate glycemic control.
Conclusion:HbA1c testing at Hospital Teluk Intan is predominantly
utilized in adult and outpatient settings. Despite substantial
testing volume, over one-third of patients demonstrated
suboptimal or poor glycemic control, underscoring
persistent therapeutic gaps. These findings highlight the
need for strengthened diabetes management strategies
and targeted quality improvement initiatives to enhance
glycemic outcomes and optimize resource utilization.
