The combination of fatigue with the serum GCSF improves the performance of serological screening for frailty

Frailty is a critical cause leading to elderly death. No drug is available to treat it, while prevention works. However, reliable blood screening and diagnostic methods for frailty are still lacking. Here, we show that the serum GCSF, in combination with the fatigue factor of the frailty scale, can improve the performance of serological screening for frailty.
