Do hemodialysis patients need a blood test every month?

Recent research suggests not necessarily.

 Routine monthly blood testing for prevalent patients on hemodialysis (HD) is not associated with a lower risk of death, hyperkalemia, cardiovascular (CV) events, or hospitalization compared with blood testing every 6 weeks, according to a new study.

Among incident patients on HD, monthly testing was associated with an increased risk of hyperkalemia, CV events, and hospitalization compared with testing every 6 weeks.

However, the optimum time interval between tests couldn't really be determined from the research, published  in the article by Thomas A, Silver SA, Perl J, et al.
