Welzo Spare Components - Purple Cap
The Welzo Spare Components – Purple Cap pack is an essential replacement kit designed to ensure that your home blood testing experience remains smooth and reliable. Many people undertaking home health tests lose time and money when collection tubes or lancets are misplaced or used incorrectly — this simple spare kit solves that problem, helping you collect a valid sample without the need to reorder your entire test. Developed to meet UK standards for medical sample collection, each component is fully compatible with Welzo’s broad range of accredited home blood tests, which are processed in MHRA and UKCA‑certified laboratories. Studies led by King’s College London and guidance from the NHS have shown that correct collection and handling of capillary blood samples is critical for accurate diagnostic results, making high‑quality spare components an important safeguard for any home user.
What Does This Test For?
While the Welzo Spare Components – Purple Cap does not test for any health condition directly, it provides all the vital equipment needed to collect a finger‑prick blood sample safely and correctly. This includes an EDTA purple‑top microtainer, which is widely used in laboratory medicine for preserving blood for tests ranging from full blood counts to hormone and nutrient analyses. By ensuring you have an extra sterile tube, lancets and cleaning supplies, this kit protects the quality of your sample so that laboratory analysis remains accurate — an approach fully supported by recommendations from the Royal College of Pathologists, which emphasises that properly collected and transported samples reduce the risk of false or rejected results. Whether you are monitoring iron levels, hormones, or general wellness markers, having a spare kit ready gives you the confidence to complete your test properly, first time.
