German scientists have developed new blood tests to predict health risks

, Aug. 23 (Xinhua) -- Researchers in Germany have found that a new blood test can predict a person's physical health for a certain period of time in the future, euronews reported. The team says the study could be a reminder to encourage them to live healthier lives.
team made a breakthrough study after analyzing blood samples from 44,468 people, The Associated Press reported. The researchers then analyzed 14 potential factors that could threaten human life, including immunity, blood sugar control, inflammation, and circulating fat.
, researchers at the Max Planck Institute for Aging Biology analyzed the blood of thousands of adults. The subjects were between the ages of 18 and 109.
, they tested the subjects' BMI, blood pressure, smoking habits, and so on. The researchers then used biomarkers from the new blood test for analysis.
analysis, each participant had a score, which ranged from minus 2 to 3. The higher the number, the more likely a person is to die early. The team then validated the predicted life span of 2 to 16 years in the trial. It turned out that more than 5,512 participants had died. The accuracy rate is 83%.
currently, doctors can try to predict whether a patient will survive next year, but predicting a patient's risk of death over the next 10 years is much harder. The researchers hope the findings will help experts improve patients' treatment options.
, who was involved in the study, said the blood tests reflected only current health and physical vulnerability. In fact, this blood test doesn't really predict how long a person will live, because factors in one's life play a role at the same time. If a blood test shows a hole in one's body, it may double the time it takes to change its lifestyle.
said the study was an exciting step for the medical community, but stressed that there was still a long way to go before the test could be put into practice.
, a researcher at the British Dementia Institute at the University of London, said biomarkers could give us insight into health and disease. However, it is limited to European data. Without further research, it may not apply to other ethnic groups.
