19.
19.
19. THERE
19. THERE ARE ALSO QUESTIONS THAT
WILL COME ALONG WITH IT.
THE ACCURACY OF THOSE TESTS AND
WHETHER THE RIGHT DECISIONS ARE
BEING MADE AS A RESULT OF THESE
TESTS.
TESTS.
TESTS. THAT IS WHY WE ARE BRINGING IN
9 HEALTH EXPERT DR. PAYAL
KOHLI.
KOHLI.
KOHLI. DR. KOHLI, IT'S GOOD TO TALK TO
YOU THIS AFTERNOON.
>> Reporter: THAT'S RIGHT KIM,
IT'S NICE TO SEE YOU.
>> TELL ME A LITTLE BIT ABOUT
WHAT THESE TESTS ARE.
SOME OF THEM TOOK DAYS TO GET
RESULTS.
RESULTS.
RESULTS. SOME OF THESE ARE RAPID?
>> Reporter: YEAH, SO WE NOW
HAVE TWO DIFFERENT TESTS.
THE FIRST IS THE SWAB TEST,
WHICH WE ORIGINALLY HAD.
THAT IS WHY THEY PUT A Q-TIP IN
YOUR NOSE AND TRY TO COLLECT
THE VIRAL SAMPLE.
LOOK AT GENETIC MATERIAL OF THE
VIRUS, AND THAT IS HOW THEY
DECIDE IF YOU'RE POSITIVE OR
NEGATIVE.
NEGATIVE.
NEGATIVE. THEY HAVE A FAST VERSION OF
THAT NOW.
THAT NOW.
THAT NOW. THAT GIVES A POSITIVE RESULT IN
ABOUT FIVE MINUTES AND A
NEGATIVE RESULT IN ABOUT 15
MINUTES.
MINUTES.
MINUTES. BUT THAT TEST WILL LOOK FOR
ACTIVE INFECTION.
ACTIVE INFECTION. YOU ONLY NEED PARTICLES FOR
THAT TO BE POSITIVE.
THE SECOND TEST IS A BLOOD
TEST.
TEST.
TEST. AND
TEST. AND THIS IS AN ANTI-BODY TEST
THAT COLLECTS YOUR BLOOD AND
LOOKS TO SEE IF YOU HAVE ANY
ANTIBODIES IN YOUR VIRUS.
THIS INDICATES PREVIOUS
INSPECTIONS.
INSPECTIONS. AND YOU CAN GET A RESULT IN
ABOUT 15 MINUTES OR SO AND THEY
WILL TELL US WHETHER OR NOT YOU
HAVE AN ACTIVE INFECTION AND
ONLY ONE WILL TELL US ABOUT THE
PREVIOUS INFECTION.
PREVIOUS INFECTION. >> SO LET'S GET INTO THE FALSE
NEGATIVE AND FALSE POSITIVE.
WHAT LEADS TO THOSE TYPES OF
RESULTS?
RESULTS?
RESULTS? >> Reporter: SO NO TEST CAN BE
100% ACCURATE, BUT WE REALLY
WANT TO TRY TO MINIMIZE THE
WRONG RESULTS.
WRONG RESULTS. FALSE POSITIVE IS WHEN YOU
DON'T HAVE THE VIRUS, BUT YOU
END UP TESTING POSITIVE ALL
DAY.
DAY.
DAY. AND
DAY. AND SO THE SAMPLE COULD GET
CONTAMINATED.
CONTAMINATED. OR YOU COULD GET CROSS ACTIVITY
OF THE ANTIBODY.
AND YOU ACTUALLY HAVE THE VIRUS
AND THOSE ARE THE ONES WE DON'T
WANT TO MISS UNDER ANY
CIRCUMSTANCES.
CIRCUMSTANCES. THOSE COULD HAPPEN BECAUSE YOU
DON'T GET ENOUGH VIRUS ON THE
SWAB IF YOU'RE SWABBING OR YOU
ARE EARLY IN THE COURSE OF YOUR
ILLNESS, TESTING POSITIVE.
>>> AND SO MY GUESS WOULD BE
THE CONCLUSION IS WE JUST IN
GENERAL NEED MORE TESTING AND
PERHAPS NEED TO REVIEW MORE OF
THE RESULTS?
THE RESULTS? IT SOUNDS LIKE WE NEED MORE
DATA?
DATA?
DATA? >>
DATA? >> Reporter: ABSOLUTELY RIGHT.
WE NEED A LOT MORE TESTING.
WE HAVE DONE MORE TESTING THAN
ANY OTHER COUNTRY.
BUT IF YOU NORMALIZE THAT, WE
REALLY HAVEN'T.
REALLY HAVEN'T. YES, MORE TESTING FOR SURE.
BUT THE OTHER THING I WANT
PEOPLE TO REALIZE BECAUSE THEY
ARE FAST TRACKING THESE TESTS,
THEY'RE REALLY NOT ALL THAT
GOOD.
GOOD.
GOOD. SO
GOOD. SO ONE IN THREE PEOPLE COULD BE
POSITIVE AND STILL TEST
NEGATIVE.
NEGATIVE.
NEGATIVE. IF YOU HAVE THE SYMPTOMS, YOU
HAVE TO ASSUME YOU ACTUALLY
HAVE THE VIRUS.
IF YOU TEST NEGATIVE.
YOU'RE NEGATIVE THAT DAY AND
YOU MAY NOT TURN POSITIVE
LATER.
LATER.
LATER. >>
LATER. >> THIS WILL ALL COME DOWN TO
COMMON SENSE.
COMMON SENSE. TRUST YOUR GUT IF YOU'VE GOT
THE SYMPTOMS.
THE SYMPTOMS. JUST QUARANTINE YOURSELF AND
LET EVERYONE ELSE STAY AWAY.
>> YOU'RE ABSOLUTELY RIGHT.
SOME DOCTORS, EVEN IF THE TESTS
COME BACK NEGATIVE, THEY ARE
TREATING THE PATIENTS AS IF
THEY HAVE THE COVID.
IT'S ABOUT THE SYMPTOMS THAT WE
REALLY HAVE TO GO OFF OF
