MONDAY, Might 3, 2021 (HealthDay Information) — Sure blood varieties could improve an individual’s threat of various well being issues, a brand new examine suggests.
The analysis confirms some earlier findings and divulges new hyperlinks between blood varieties and illnesses, in keeping with the authors of the examine revealed April 27 within the journal eLife.
“There’s nonetheless little or no info out there about whether or not individuals with RhD-positive or RhD-negative blood teams could also be liable to sure illnesses, or what number of extra illnesses could also be affected by blood sort or group,” mentioned first creator Torsten Dahlén, a doctoral pupil at Karolinska Institute in Stockholm.
