Product introduction:Colloidal gold-based fluorescence assay for drug detection plan.
Colloidal gold-based fluorescence assay for drug detection plan
Colloidal gold-based fluorescence assay for drug detection plan is developed by our company using a combination of colloidal gold method and fluorescence immunoassay to achieve the goal of rapid detection and screening of hair drug samples in accordance with the relevant standards of the Ministry of Public Security's Document No. 938 of 2018. This product and scheme meet the needs of public security agencies for hair drug testing. Firstly, a qualitative test is performed using the colloidal gold method to quickly obtain results. If necessary, accurate quantitative testing or result verification can be conducted using fluorescence analysis. The combination of both methods eliminates the need for repeated hair processing, resulting in faster results, higher accuracy, and more convincing qualitative and quantitative testing.
1. Sample pre-processing
1.1 Wear disposable gloves, cut hair within 3 cm of the back of the head at the root, and divide into two parts A and B, each containing no less than 50 mg.
1.2 Take 10mg of hair and put it into a centrifuge tube with a grinding bead, and insert the centrifuge tube into the adapter hole of the grinder.
1.3 Adjust the instrument to the best state, and grind hair according to the preset instrument parameters. When the grinding time is over, the instrument stops automatically and the centrifuge tube is taken out.
2. Colloidal gold qualitative analysis
2.1 Add 0.5ml of buffer solution to the centrifuge tube of ground hair and shake it a few times. Use a test tube to aspirate the hair solution from the centrifuge tube, drop 3-4 drops into the hair colloidal gold plate, and observe the running situation.
2.2 Result interpretation:
Note: Colloidal gold testing is used for large-scale, rapid qualitative screening of hair samples, followed by secondary confirmation and quantitative analysis using fluorescence method. This is particularly useful for suspected samples (negative results with slightly lighter T-lines). The use of fluorescence method provides precise quantitative analysis, resulting in more accurate test results.
5. Advantages of combined testing
5.1 High accuracy: The two methods complement and verify each other, resulting in more reliable results. Especially for secondary confirmation of suspected samples, the test results are more accurate.

5.2 Rapid Economy: The hair grinding machine can process hair samples in batches, with a maximum of 24 samples processed simultaneously. After processing the samples, the liquid drop colloidal gold test plate can be used to quickly read the results. Only a small number of cases require further confirmation with fluorescence, greatly saving costs. 5.3 Fitting needs: According to user needs, flexible use of two methods for qualitative and quantitative detection, with a diversity of testing methods.
