Everything you need to know about antigen tests that you can buy in pharmacies
The antigen tests can already be purchased in pharmacies from this Tuesday and will have a price that will range between 6 and 10 euros, although the cost will not be regulated by the Government, but will be set between the one that the laboratories determine for sale. to the pharmacies and the retail price set by them. They do not need a prescription and will begin to be dispatched from the moment the Council of Ministers approves the decree that will allow their sale without a prescription on Tuesday.

How to know if a pharmacy antigen test is positive
When performing this type of test, it must be taken into account that there is a possibility that false positives and false negatives may be obtained when a person without symptoms or with a low viral load is tested.
In the case of a positive result, two horizontal colored lines will be displayed: the test line (T) and the control line (C). On the contrary, if it is negative, a single horizontal colored line will appear, the control line (C). Test results are obtained 15 minutes after the test is performed.
