What time is it in your body?
The first simple blood test to identify your body's precise internal time clock as compared to the external time has been developed by Northwestern Medicine scientists.
The test, TimeSignature - which requires only two blood draws - can tell physicians and researchers the time in your body despite the time in the external world. For instance, even if it's 8 a.m. in the external world, it might be 6 a.m. in your body.
"This is a much more precise and sophisticated measurement than identifying whether you are a morning lark or a night owl," the lead author of the study has said.
Processes in nearly every tissue and organ system in the body are orchestrated by an internal biological clock, which directs circadian rhythm, such as the sleep-wake cycle. Some individuals' internal clocks are in sync with external time but others are out of sync and considered misaligned.
The new test for the first time will offer researchers the opportunity to easily examine the impact of misaligned circadian clocks in a range of diseases from heart disease to diabetes and Alzheimer's disease. When the blood test eventually becomes clinically available, it also will provide doctors with a measurement of an individual's internal biological clock to guide medication dosing at the most effective time for his or her body.
