It’s meant for the normal inhabitants with out the intervention of a well being employee, so to a sure extent it reduces the care strain of well being facilities.

When ought to it’s used?

In accordance to the data revealed by the Spanish Company for Medicines and Well being Merchandise (AEMPS), we should do the test throughout the first 7 days after an infection or in the first 5 days with signs. They aren’t beneficial in asymptomatic circumstances, since they might give false negatives, in addition to in circumstances with low viral load.

How do i do it?

The kind of pattern that’s collected is nasopharyngeal (an approximate depth of 3cm), oropharyngeal, nasal or saliva, and we will carry out it at dwelling.

We are going to perform the test strictly following the directions for use, and we should do it instantly after taking the pattern. It is vitally vital that we know that the efficiency of this test will rely on the kind of pattern obtained and its appropriate execution.

How do I interpret the consequence?

TARs have 2 coloured strains: the test line (T) and the management line (C). Relying on the strains which are displayed, we will discover the following conditions:

2 coloured strains: If the C line and the T line are seen, the result’s thought of optimistic and we might be thought of a suspected case of COVID-19. We should isolate ourselves and phone the well being providers in order that we might be evaluated and confirmed or not whether it is an lively an infection.

Line C seen and line T in white: The result’s thought of destructive, but when we current any signs or we’re in shut contact with a confirmed case, we should stay remoted and phone the well being providers in order that the an infection is confirmed or not via a confirmatory diagnostic test and / or medical analysis. In no case ought to this destructive consequence be used to shorten or finish the isolation interval. In abstract, a destructive consequence won’t be taken under consideration to exclude an lively an infection.

Line T seen and line C clean: This result’s thought of invalid and we should always repeat it, since the management line (C) should all the time be seen.

Clean test: If after the test no line is displayed, neither the T nor the C, this result’s thought of invalid and we should always repeat it, since the management line (C) should all the time be seen.

How do I act on the consequence?

These self-diagnostic assessments are usually not a panacea. The potential of acquiring false positives and false negatives should be taken under consideration, particularly in circumstances of low viral load or if the test is carried out with out signs. As well as, it will be important to do not forget that the efficiency of this test will largely rely on the kind of pattern obtained and its appropriate execution.

What we should be clear about is that if we current any symptom appropriate with COVID-19 or we’ve got been in shut contact with a confirmed case, we should isolate ourselves and phone the public well being service.

In these circumstances, we will bear ART, however even when we get hold of a destructive consequence, it doesn’t exclude an lively an infection and we should wait for the evaluation by the well being providers.

A destructive test may give a false sense of safety and lead to riskier conduct than with out the test. Because of this, even when the result’s destructive, we should keep the guidelines of social distancing and the use of masks even after a destructive test.

On the different hand, a optimistic consequence would lead us to be a suspected case and never a confirmed case. It’s the well being providers that ought to consider us and make sure or not this an infection via a test (presently PCR is the most dependable) and / or medical analysis.
