1. More ventilation. The temperature is 20-25℃ during the day and 12-14℃ at night. 2. Water as little as possible after watering thoroughly before sowing until the seedlings grow real leaves. When the soil is dry and cracked, water less. 3. Give plenty of sunlight to prevent being injured. The ultraviolet rays in the sun can inhibit the growth of vegetable seedlings. Use sunshade nets and other measures when the sun is in summer. 4. There must be a small amount of nitrogen fertilizer in the soil, which can be applied as a late topdressing. 5. When sowing, spread as evenly as possible, with loose spacing, which can increase air flow, reduce temperature and prevent excessive growth.

These links would not have been made if viral particles were looked for via PCR methods. This is due to the fact that the patient's immune defence might be successful in eliminating the virus and hence removing any trace of where it came from. However, when specific antibodies are searched for in the same patient, they will be able to be detected because they stay within the blood for several years. Commercial immunoassay tests to detect COVID-19 include a dual ELISA test to be performed. This detects specific IgA and IgG against the virus in the blood of infected patients. There is also an automated fluorescent immunoassay system to measure quantitatively or semi-quantitatively the concentration of the targeted analyte, which can be the viral antigen or IgM/IgG. antibody diagnostic kit, rapid antibody test kit, rapid antibody diagnosis,covid-19 antibody diagnosis, antibody detection kit Shenzhen Uni-medica Technology Co.,Ltd , https://www.unimedicadevice.com
