Nancy shares her story about using a Forth blood test to check her health after an illness and monitor cholesterol.
September 2, 2025

I wanted to check my health markers after a nasty case of whooping cough. I also wanted to monitor my genetically slightly high cholesterol and keep an eye on my heart health
I was suffering from a little fatigue. I put this down to being a fitness instructor, teaching over 25 classes a week and working 7 days a week but I wanted to be sure there wasn’t anything else to be concerned about. I also wanted to be sure there were no lingering impacts of the whooping cough.
It was reassuring to find that all my levels were back to normal and within health ranges. What was particularly interesting was that the Dr flagged up some markers that, whilst in the healthy range, were lower than he’d expect given my lifestyle etc. My ferritin levels were lower than expected and given my high levels of exercise it was likely I was suffering from sports anaemia. This wasn’t something I was aware of and had I not had the dr’s report alongside the tests I’d never have realised. He suggested I take a specific type of iron supplement to help this.
I started taking the recommended iron supplement. I’ve noticed that my fatigue has definitely lessened and I’m certain it’s linked to that. I love that I’ve the knowledge now to help manage my health better.
I love being able to track my health in this way – it’s easy and convenient
