Here’s What You Need To Know About COVID-19 Tests In The Philippines
The key out of it? Testing. The World Health Organisation (WHO) has stressed the importance of mass testing in the fight to flatten the curve. One of the organisations at the helm of this movement is Project ARK, a private sector-led initiative that aims to introduce rapid antibody testing to companies and barangays in a bid to contain the spread of the virus. Today, Dr. Minguita Padilla, ophthalmologist and head of the medical team at Project ARK, tells us about what there is to know about COVID-19 testing right now.
What parts of the body does COVID-19 affect?
Currently, the WHO has released more symptoms for COVID-19. The full list includes fever, dry cough, and tiredness. They have also added aches and pains, nasal congestion, headache, conjunctivitis, sore throat, diarrhea, loss of taste or smell or a rash on skin or discolouration of fingers or toes to the list.
Was the lockdown necessary?
On a macro level, what is the best way to handle COVID-19? How does our country compare?
It would also be best for test results to come out within 4-8 hours but turn around time within the past few months had been 5-7 days, and sometimes as long as 2 weeks. As of 2 May 2020, there has also been a backlog of 8,000 test results yet to be released.
What are the different types of tests available for COVID-19?
IgM can be found in patients who are positive for COVID-19 by RT-PCR and are still infected and infectious. IgG is found in those previously tested as positive, but who have since recovered. Those with IgG can donate blood to the Philippine General Hospital for plasma therapy to help those who are currently positive but have not yet recovered.
What should you do after you use a rapid antibody test kit?
- If you have no symptoms, are negative for IgM, and positive for IgG then you are probably infected and developing immunity. It is best to self-isolate.
- If you have no symptoms, are positive for IgM, but are also positive for IgG, then it’s best to self-isolate for another 14 days, take another rapid antibody test after that time, and check the results again.
- If you have no symptoms, are positive for IgM, and are negative for IgG, then you are considered infected. It is best to self-isolate for 14 days and take an RT-PCR swab test.
- If you have no symptoms, are negative for IgM, and are negative for IgG then you’re not likely to be infected but may consider taking a retest after 7 days.
- If you have symptoms, then it is always best to self-isolate.
What are the advantages and disadvantages of these tests?
The advantage to the rapid antibody test is that it’s quick, relatively inexpensive (should cost around Php400 – Php700), and easy to use. However, the disadvantage lies in the fact that accuracy depends on the sensitivity of the kit itself so the brand and manufacturer are quite important. It may also result in false negatives if one tests too early and the immune system has not had time to generate antibodies.
Who should be tested?
- All asymptomatic or symptomatic persons who have been in close contact with a confirmed COVID-19 patient
- All asymptomatic or symptomatic persons who have been in close contact with a probable confirmed COVID-19 patient. According to the WHO, probable confirmed patients are suspect patients who have been tested for COVID-19 but with inconclusive results. Another definition for a probable confirmed patient are those who have tested positive for COVID-19, but the test was not conducted in an officially accredited laboratory for confirmatory testing. A suspect case for whom testing could not be performed (for any reason) is also a probable confirmed patient.
- All symptomatic persons
- Those with high-risk including diabetics, hypertensives, the immunosuppressed, the obese, and the elderly
Is Manila ready for general community quarantine?
Right now, it is best for everyone to stay calm but vigilant by wearing masks, constantly washing hands, and observing proper social distancing. It’s also best not to take the state of general community quarantine as an excuse to let our guard down, as carelessness and absent-mindedness can lead to another surge of infections, and in the worst case scenario, another lockdown.
