The government has expanded the mandatory testing group earlier, and restaurant staff and construction site workers have to undergo regular testing, which has greatly increased the demand for testing. Many people reported that after submitting the sample bottles, the test results were received after many days; there are also test reports. The date is wrong.

He Boliang, director of the Infection and Infectious Diseases Center of the University of Hong Kong, said on a commercial TV program this morning (4th) that the delay is unacceptable.

He pointed out that some studies have shown that if samples are stored at room temperature for more than 24 hours, they will have negative effects and even false negative results. "Doing nothing is doing nothing and making money." He believes that the government must strengthen supervision of laboratory testing institutions.

Lin Miaoyin, the former assistant chief interview director of CATV, also issued a document saying that the test results were received after 8 days; and when looking through the electronic test records, they found that the sample collection date was incorrect. The same day until the result.

He Boliang said on the commercial channel program "Starting on a Sunny Day" this morning that detection delays cannot be accepted, and the report should include the date of collection (sample), the date of receipt (sample), and the date of reporting.

He Boliang said that if the samples are stored at room temperature after receipt, it is a waste of resources in disguise, and false negative results are more likely to occur.

He pointed out that according to Beijing's research and analysis, if the sample is stored at room temperature for more than 24 hours, it will have a negative impact; if the virus content of the sample is not high, and it is stored at room temperature, there will be a quarter chance of a false negative result. .

He believes that the relevant situation affects epidemic prevention and is not up to standard. "Doing nothing is equal to doing nothing, but also making money." He urged the government to strengthen supervision.

He Boliang said that people who are worried about allergies should balance the risks and effects before deciding whether to vaccinate.
