Protein level in blood can predict a person’s age

A team of researchers from the Stanford University School of Medicine has developed a new method for estimating a person’s age using the proteins circulating in the blood. The scientists refer to it as the’ proteomic clock’ that relies on protein levels that rise and fall in the lifetime of a person. The scientists conclude that such changes in the levels of various proteins may not only characterize the aging process, but may also possibly cause it. They developed the clock by looking at composite levels of proteins within groups of people rather than doing so individually. The study proved capable of predicting people’s ages within a range of three years.
