Summary

This study looked at whether levels of nucleosomes and free DNA in the blood change from month to month in healthy people and in those who have had a blood clot (venous thromboembolism). Researchers measured these markers monthly for six months in 15 healthy volunteers and 15 patients with a history of clots. The goal was to see if these markers are stable enough to be useful for monitoring clot risk.
