Bengaluru: While the RT-PCR test in people shows significant symptoms of Covid-19 disease which returns negative even while CT scan confirms infection is not new, the Jayanagar General Hospital managed by the government has eight cases like that in the past week , Two of these people have died and the doctor said this was unusual considering the incident was low.
So many false negatives in a short range are not seen before, the hospital authority claims.
“Eighth case has a typical Covid-19 symptom and requires hospital admission.
We do CT scans in all these cases that show infection.
However, we lost two patients,” said Dr.
Sudha Heroor, Nodal Officer for Covid-19, General Hospital Jayanagar.
BBMP is now randomly collecting positive patient wipers for genome sequencing, but sequencing needs to be done in these patients to check whether they are infected with different variants, the hospital said.
Caseshowever Cluster, Dr.
CN Manjunath, Nodal Officer for Lab and Testing, Covid-19 State Duty Unit, said this could be among such a group of cases, and they might not represent all Covid positive cases.
“People who undergo the RTPCR test that raises false negative results are treated as Covid-19 patients after CT scanning shows infection.
This applies 5-8% of cases throughout the state.
Sometimes, RT-PCR retest can help.
Syndrome approaches based on scans and scans Symptoms of CT, regardless of the RT-PCR report, now it is well established, “said Dr.
Manjunath.
Doctors say False-negative reports can be misleading because patients tend to ignore symptoms given the weight dependence on RT-PCR testing only in Covid-19 management.
RT-PCR is a gold standard for testing Covid-19.
KITDR Quality Raghu J, Senior Consultant, Internal Medicine and Infectious Disease Specialist in WORLD SAKRA, the mischievous RT-PCR results are seen in about 10-15% of cases.
The quality of the RT-PCR kit used for tests is also important in the final result, he added.
“All patients are negative for Covid RT-PCR tests, but have suggested symptoms to take CT scans,” Dr.
Raghu said.
“The False-negative report is not confirmation and symptoms of people need to be considered.
We explain this to the patient’s family.
However, even in such cases, not everyone will need hospitalization.
Symptoms, comorbidity, oxygen saturation, Disease Development and CT’s severity assessment All are taken into account.
“When all-imported, according to Dr.
Satyanarayana Mysore, pulmonologist, negative results can occur when the swab is taken on the ninth day after one is infected or if the swabs are tested for a long time after they are collected.
“If the person is symptomatic and if the results of RT-PCR negative for Covid, the CB-NAAT test must be done, which can provide more clarity.
CT scans in such cases show infection and care must begin,” said Dr.
Mysore.
He said that there were a number of cases where RPCR reports showed negative and such cases had been explained to the BBMP nodal officers so that the ID number of government patients could be issued.
In some cases, people who have reported the negative for RT-PCR have been tested positively in covid antibody tests, which means the virus may have been lost but things after the effect.
When contacted, Dr.
BK Vijendra, Chief Health Officer, BBMP, said there was no increase in fake-negative RT-PCRs since the hit pandemic.
“The proportion of such cases is 2-3% of the total cases in the BUMP limit.
There are no improvements in such cases and the role of the variant cannot be determined with current data,” he said.
