Au5800 automatic

NLR and CAR levels within one week before treatment were retrieved from medical records. NLR was defined as neutrophil counts divided by lymphocyte counts. And neutrophil and lymphocyte counts were measured automatically using Mindray CAL8000 hematological analyzers (Mindray Corporation, Shenzhen, China). CAR was defined as the ratio of serum C-reactive protein (CRP) level divided by the serum albumin (Alb) level. Both CAR and Alb were measured automatically using Beckman Coulter AU5800 automatic biochemical analyzer (Beckman Coulter Corporation, California, USA).

Using medical records, we collected clinical data, including age, sex, duration of diabetes, and medications, and blood glucose values using the iHealth software of the “Trinity Care” patient management system of our hospital, and weight, height, and brachial artery blood pressure of the right upper limb were measured by trained personnel. Fasting venous blood was collected and tested at the central laboratory of Chu Hsien-I Memorial Hospital, Tianjin Medical University. A Beckman Coulter AU5800 automatic biochemical analyzer (Beckman Coulter, Kraemer Blvd, Brea, CA, USA) was used to detect glycosylated serum albumin (GA), liver and kidney function, and blood lipids. Patients’ HbA1c levels were tested using a Sysmex XN instrument (Sysmex, Kobe, Japan). HbA1c test program conformed to the standard of the National Glycohemoglobin Standardization Program.
