Methods: A retrospective review of records of a private laboratory named Labcorp Diagnostics Pvt Ltd covering the period 1st to 31st January 2022 was done. Laboratory data of study participants who were undergone Hemoglobin A1c (HbA1c), Serum Cholesterol, and Thyroid Stimulating Hormone (TSH) during the study period were retrieved and analyzed using Epi Info V7 Software. Results: In the present retrospective review, laboratory data of 169 study participants who were undergone Hemoglobin A1c(HbA1c), Serum Cholesterol, and Thyroid Stimulating Hormone (TSH) tests were analyzed. The mean Hemoglobin A1c(HbA1c) level was 6.07±1.294%. 61(36.1%) had their HbA1c level in the normal range, 77(45.6%) had HbA1c level below the normal range while only 31(18.3%) study participants had their HbA1c level above the normal range. The mean Serum cholesterol Level was 191±47.547 mg/dL. 75(44.4%) had their Serum cholesterol Level in the normal range, 94(55.6%) had Serum cholesterol Levels above the normal range and none of the study participants had their Serum cholesterol Level below the normal range. The mean Serum TSH Level was 2.950±2.156 mIU/L. 149(88.2%) had their Serum TSH Level in the normal range, 16(9.5%) had Serum TSH levels above the normal range while only 4(2.4%) of the study participants had their Serum TSH Level below the normal range. Conclusion: Present study concluded that almost one-fifth of the study participants had their Hemoglobin A1c (HbA1c) level above the normal range, more than half of the study participants had their Serum cholesterol Level above the normal range while almost one-tenth of study participants had their Serum TSH Level above the normal range.
