Background: Diabetes mellitus is a common disease and it is a major cause of morbidity; several studies indicate that diabetes is a likely under reported cause of death. Chromium's is important trace element to control diabetes mellitus and metabolism of carbohydrate, lipid and protein. Objective: The purpose of this study was to understand the relationship between serum chromium, with HbA1c, Total cholesterol and Triglycerides among type 2 diabetes patients among diabetic patients. Methodology: This is cross-sectional study done in Jabber Abu Ezz Centre for treatment and care of diabetics in Khartoum-Sudan. Four hundred subjects were enrolled in this study; one hundred subjects were normal healthy as control group, and three hundred subjects diabetic patient type 2 as test group; demographic and biochemical data were collected; serum chromium, Glycosylated Haemoglobin (HbA1c), Total cholesterol Triglycerides, were determined by using NYCOCARD READER II, spectrophotometer (Biosystem 310) and spectrophotometer 210-VGP. Result: In this study there is significant parameters level means of FBS HbA1c, Total Cholesterol, Triglycerides and Chromium of the test groups when compared with healthy control groups subjects (P = 0.001, 0.018, 0.01, 0.011, 0.004), respectively. Significant negative correlation is between FBS, HbA1c, Total Cholesterol, Triglycerides and Chromium (r = −0.555, P value = 0.003), (r = −0.668, P value = 0.002), (r = −0.335, P value = 0.004) and (r = −0.774, P value = 0.002) respectively. Conclusion: There was
