&lt;p style=&quot;text-align:justify&quot;&gt;&lt;em&gt;Low level of RT-PCR re-testing in persons who are testing antigen negative will underestimate cases, says COVID-19 task force member&lt;/em&gt;&lt;/p&gt;

&lt;p style=&quot;text-align:justify&quot;&gt;Only 1 in 200 of those who tested negative in an antigen test in Delhi to detect possible coronavirus cases were re-tested, a fraction that epidemiologists say is too low given what is known about the disease. From June 25, daily cases appear to have peaked at 3,390 and steadily declined to 1,790 as of 15 July.&lt;/p&gt;

&lt;p style=&quot;text-align:justify&quot;&gt;Delhi formally began using antigen testing kits on June 18 and has accelerated their use since July. While these tests dominate daily testing, using them widely without following up with adequate retests contradicts Indian Council of Medical Research (ICMR) guidelines on use of the test, experts told The Hindu.&lt;/p&gt;

&lt;p style=&quot;text-align:justify&quot;&gt;From June 18- July 16, Delhi has conducted 305,820 Rapid Antigen Detection Tests (RADT) &amp;mdash; a quicker complement to the standard RT-PCR (reverse transcription polymerase chain reaction) test that while most accurate takes as many as 24-48 hours to deliver a verdict &amp;mdash; to check for the COVID-19 virus. Of these, 285,225 tests came &amp;lsquo;negative&amp;rsquo;. Of them, 1,670 (or about 0.5%) were chosen for re-test by RT-PCR and 262 of these were confirmed positive, according to the most updated figures as on July 16 confirmed by The Hindu.&lt;/p&gt;

Fewer COVID-19 re-tests mar Delhi’s testing strategy -Jacob Koshy and Nikhil M Babu

-The Hindu Low level of RT-PCR re-testing in persons who are testing antigen negative will underestimate cases, says COVID-19 task force member Only 1 in 200 of those who tested negative in an antigen test in Delhi to detect possible coronavirus cases were re-tested, a fraction that epidemiologists say is too low given what is known about the disease. From June 25, daily cases appear to have peaked at 3,390 and steadily declined to 1,790 as of 15 July. Delhi formally began using antigen testing kits on June 18 and has accelerated their use since July. While these tests dominate daily testing, using them widely without following up with adequate retests contradicts Indian Council of Medical Research (ICMR) guidelines on use of the test, experts told The Hindu. From June 18- July 16, Delhi has conducted 305,820 Rapid Antigen Detection Tests (RADT) — a quicker complement to the standard RT-PCR (reverse transcription polymerase chain reaction) test that while most accurate takes as many as 24-48 hours to deliver a verdict — to check for the COVID-19 virus. Of these, 285,225 tests came ‘negative’. Of them, 1,670 (or about 0.5%) were chosen for re-test by RT-PCR and 262 of these were confirmed positive, according to the most updated figures as on July 16 confirmed by The Hindu.
