Training hard can feel unpredictable. One week your sessions land well, the next you are carrying fatigue and recovery does not match the work you are putting in. Without objective data, it is easy to keep pushing when the limiting factor is actually in your underlying blood health, fuelling, or inflammation.

Sport PLUS is a home blood test designed to give you a clear view of the foundations that support performance. Using a home test kit for testing from home, it checks markers linked to oxygen delivery and general blood health, including haemoglobin and a full blood count, so you can understand whether your capacity to transport oxygen and support training load looks robust. It also looks at immune status, which can shift with heavy training blocks, poor recovery, or illness risk.

Crucially, Sport PLUS measures long-term blood sugar control via HbA1c. Even if you feel fit, glycaemic control can influence energy stability, training quality, and how well you recover between sessions. The test also assesses key vitamins and minerals involved in red blood cell production, energy metabolism, and tissue repair, including ferritin, active B12 and folate, alongside albumin and calcium, helping you identify whether nutrition or absorption may be holding you back.

Finally, it includes hs-CRP, a marker of low-grade inflammation. This can add useful context when training feels harder than it should, or when you are trying to judge whether fatigue is simply load-related or something more systemic. Taken together, Sport PLUS helps you focus your next training and nutrition decisions on what your biology is actually doing, not what you are guessing.
