Blood clots and blood thinners

A blood clot is the problem, and a blood thinner is the medicine taken for it, yet searches mix the two. The seven questions below keep them apart and show where one leads into the other.
What the clot is
medlineplus.gov defines it this way: "A blood clot is a mass of blood that forms when platelets , proteins, and cells in the blood stick together."
Five questions stay with the clot. What is a blood clot? and Why do blood clots form? cover what it is and where it comes from. What symptoms can blood clots cause?, How are blood clots diagnosed? and How are blood clots treated? follow in the order a patient would meet them.
What the medicine is
Two questions switch the subject to the drug. What are blood thinners? is the definition, and How can blood thinners be taken safely? asks about use.
Treatment is where the two sets meet. NHLBI pages on venous thromboembolism treatment and venous thromboembolism diagnosis sit beside a my.clevelandclinic.org page on deep vein thrombosis and the MedlinePlus entry on blood clots.
The comparison to keep
Ask whether a question is about the clot or the medicine. How clots are treated and what blood thinners are can read alike, but the first names a condition and the second names a drug.
