Cystatin C
£65.00
A creatinine-independent kidney marker, unaffected by muscle mass — which matters if you carry a lot of it.
Cystatin C in the Biomarker Guide — what it is, why it is tested, and what moves the number.
Add-on markers can only be added to venous samples.
Timing
No fasting needed and no particular time of day. Unlike creatinine, cystatin C is not pushed up by a meal of cooked meat, and it does not move with muscle mass.
Turnaround: the lab reports this test within 24 hours of receiving your sample, counted in working days. Most samples reach them within about 3 days of posting. Full detail on our Turnaround Times page.
