Tiredness and unexplained symptoms

Common reasons for feeling persistently tired, or lacking energy may be due to an iron deficiency, thyroid problems or coeliac disease, but there can be many other reasons as well. Always speak with your doctor if you are anxious about your health or concerned about your symptoms.

Let's make self-testing better

Our tests are based on the same principles used by hospital labs, and provide reliable, meaningful results, but self-testing is not meant to replace established NHS healthcare pathways. Always consider what a positive or negative result will mean to you before testing, and be aware of the limitations of the test you are using.
