Health and Family Welfare Ministry has taken a decision to use one time RT-PCR based pooled sampling for surveillance purposes of migrant workers and international passengers who are in institutional quarantine facilities. The pooled sampling will also be conducted for surveillance purpose in green zones districts which have not reported any corona case in last 21 days.
The pooled samples from 25 specimens will be tested in the lab by the RT-PCR method. The report will then be conveyed to the quarantine facility within 24 hours.
If any of the pooled samples are tested positive, then individual samples from the preserved pool would be tested. Samples will be preserved in the laboratory.
“The samples will be aliquoted and thereafter pooled samples from 25 specimens shall be tested in the laboratory by RT-PCR method. The report will be conveyed to the quarantine/concerned facility within 24 hours. If any of the pooled samples tests positive, individual samples would be tested from the aliquoted samples preserved in the laboratory,” say the health ministry guidelines.
