Best place for blood tests, post cycle? UK

Hi all,

What’s the best place for a blood test? I’m thinking of venous (which I can get done privately instead of a finger prick)

I’ve heard medicheck is hit or miss and just want some reliable/accurate places for home testing kits - for hormones/test.

I don’t want to waste £150+ on tests that aren’t reliable or using good labs

Anyone had any good personal experiences with home testing kit places?
