Abstract Background: The values of electrolytes are measured by both the arterial blood gas analyzer and the auto-analyzers, in arterial and venous blood respectively. Literature reports suggest controversies in comparisons between the results. Concerns have been increased about the precision of the instrument due to difference in results of laboratories, in addition to the time consumed. Materials and Methods: This is a prospective observational study on serum and ABG electrolytes in samples from 53 (34 Male and 19 Female) patients admitted to ICU at King Abdul-Aziz Medical City (KAMC). The analysis was done in Central Laboratory. The results from patients ’ file were uploaded to SPSS from excel sheets and statistical analysis was done. Results and Conclusion: The age of patients varied between 14 years and 87 years in both the sexes. The sex wise frequency was 64.151 % (males) and 35.85 % (females). The pathological reports showed highest incidence of post-Motor Vehicular Accidents (MVA) followed by Community Acquired Pneumonia (CAP) and Respiratory Failure (RF). Comorbidities were infrequent
