Can we know if we have passed the Covid-19 by looking at our nails?

During these months, more and more investigations reveal whether we have passed the Covid-19, because those who have not manifested symptoms may not have found out. Then there are those who have had it mildly and have been able to confuse the disease with a cold. Now it seems that we can know if we have passed the Covid-19 by looking at our nails. How? The normal thing is to carry out an antibody test and in this way we can know that we have passed the disease and also make it clear in the vaccination passport to be able to travel with greater safety to different countries of the EU, but there are more ways to find out . This is what Dr. Karan Raj tells us, who offers all kinds of videos on a well-known social network of videos and music. The doctor, through his account, offers information on health and for this reason he has many followers. One of his latest videos is related to the ways of knowing if we have passed the Covid-19 and according to him we can know them through our nails, he attributes it to the well-known white lines of the fingernails, specifically of the that spread horizontally and according to the doctor this could be a sign that a person has had an infection, and he also attributes it to the fact that it could be a sign that they have or have passed Covid-19. It is supported by the idea that people who recover from this disease are left with a clear or white horizontal line on the nail, these are called Beau’s lines and they arise when there is an infection. But it should be noted that the doctor’s method, even if it is a health worker, is not an absolute confirmation and he recognizes it himself, that is, he says that it may be a test but not a confirmation because for this a test must be carried out, such as as we all know.Well, beyond the Covi-19, the white lines of the nails can indicate many other things. He himself comments that if we are not sure if we have been infected by the coronavirus and we are suspicious then we should perform an antibody test It is that simple and safe, because the rest of things lack confirmation and especially scientific evidence although it is say a doctor. The truth is that Raj has become really popular and all the things he talks about are going totally viral.
