hiv primary screening reagents How many generations of enzyme-linked reagents are used in the laboratory of Ya'an People's Hospital? Thank you. Please tell me if you know.

Nowadays, municipal hospitals are predominantly three-generation

If it is four-generation

It will definitely be stated

Because less than one-tenth of the hospitals in China are using ELISA four-generation

So if it is four-generation

It will definitely be stated again and again in order to show its own advancement

However, it is not possible for a hospital to use the same reagent for the first time in the future. Even if it's 3rd generation

it can be ruled out after a month and a half of high risk
