Points to note when choosing a clinical biochemical kit:

1. First read the kit instructions carefully. The composition, method and performance indexes of the kit are analyzed. Whether it is used for manual operation or for clinical biochemical analyzer, which belongs to the latter, check whether the experimental parameters are consistent with the parameters of the unit's clinical biochemical analyzer. Generally choose the conventional method kit recommended by the Ministry of Health Procurement Center. Some projects do not establish a reference method and do not recommend a conventional method. A recognized test method kit should be used.

2. Are there any approval numbers from the Ministry of Health? All kits that have been included in the scope of examination and approval of in vitro diagnostic reagents for clinical testing by the Ministry of Health should not be used unless they have a production approval number.

3. Pay attention to the influence of the season on the quality of the reagents and prevent the reagent kits from deteriorating during transportation.

4. Under the premise of ensuring the quality of the kit, buy low-cost products.

5 According to the daily work load of the unit, the amount of the instrument used, the stability period of 4 â„ƒ after the reagent is reconstituted, and other factors, select the appropriate packaging and purchase the products that have recently been shipped.
