Scientists Claim Blood Test Can Detect Circadian Rhythms.

reports a study published in PNAS describes a new computer algorithm developed by scientists at Northwestern University that “uses blood sample data to predict someone’s circadian rhythm.” ABC News explains, “Disruption of a normal rhythm may be a factor in many diseases: insomnia, heart disease, and even neurological disorders like dementia have all been linked to a misaligned circadian rhythm.” If the algorithm “works as well as they believe, physicians could know ‘what time it is’ within someone’s circadian rhythm, and use it to examine the impact of a disrupted ‘clock’ on various diseases.” https://abcnews.go.com/Health/scientists-developed-blood-test-detect-internal-body-clock/story?id=57731003
