[0027] Example
[0028] A method for constructing a tuberculosis risk prediction model based on iron metabolism indicators includes the following steps:
[0029] (1) Collection and processing of samples;
[0030] In this example, the population was included on an empty stomach for 12 hours, and 5 mL of venous blood was collected using a vacuum tube containing separation gel. After the blood sample was placed at room temperature for 30 to 45 minutes, centrifuged at 1000 g for 5 minutes, separated the serum, and placed a clean test tube with a lid for low-temperature storage; Store at 8°C for one week.
[0031] (2) Determine the iron metabolism index from the sample, specifically including the data of three metabolism-related indexes, namely serum iron, transferrin, and ferritin; the detection method of serum iron is complexation method, and the detection method of transferrin is immune Turbidimetric method, the detection method of ferritin is chemiluminescence method; the specific ste...
