About Rainbow Labs

Rainbow Labs is a CQC-registered diagnostics company offering at-home blood test kits and in-clinic blood tests across the United Kingdom, with prices starting from £49 for vitamin D tests and £89 for comprehensive health packages. Customers receive results within 2-3 working days after the laboratory receives their sample, with NHS-trained GPs reviewing results and providing personalised recommendations. The company offers free and discreet delivery on all orders and includes a 14-day cancellation window with a £20 deduction for kit and postage costs if you haven't sent your sample for testing. However, customer reviews highlight significant concerns about delivery delays, missing test results, and inconsistent customer service responsiveness.

A quick guide to help you decide if Rainbow Labs fits your needs before you buy.

Who should shop at Rainbow Labs

Worth knowing before you buy
