 To determine the frequency of pre-analytical errors in haematology and chemistry at Hayatabad Medical Complex Peshawar.


A descriptive cross-sectional study was conducted at the MTI/Hayatabad Medical Complex (HMC), Peshawar, from February to July 2022. Through the purposive sampling technique, 480 samples were collected. Each sample was tested to analyse and assess errors in haematology and chemistry. For statistical analysis, SPSS version 26.0 was used.


Four hundred eighty samples were studied during the project with the following pre-analytical errors, mainly 27.11% insufficient quantity, 22.91% clotted sample, 17.70% hemolysis, and 12.5% of the investigation were incorrect vacuum sealers or collection tubes. The analysis's error rate for the EDTA mix samples was 15.83, and 03.95% was the Hypervolumic sample in the study.


It was concluded that human error, technical error, and insufficient staff knowledge were the major errors in haematology and chemistry.
