Thanks for your question. Good of you to write in. Aspirin
is a good drug so much so it used to be available OTC most of the countries but after is effects as blood thinner became established chances of takin wrong reason for example in cases of brain hemorrhage
or a small bleed in brain and taking it by person who are alllergic to it icrased. Now in some developed countries aspirin cardiovascular is a prescription drug. My suggestion to you meet the doctor who advised you test in first place and discuss the report with him/her, if drug is advisble there is is no reason for you you not to take it. Do take it.
With best wishes.
