It doesn&#x27;t make sense to me to restrict access to common diagnostic information based on the risk of people attempting treatments not approved by the NHS. The potential list is endless: Weighing machines, because some people are anorexic. Glucose monitors, because some people might not understand how to manage their blood sugar. Mirrors, because someone might misinterpret the discoloration of their tongue.<p>I would suggest it is a basic civil liberty to be allowed to know about the nature of the blood pumping through your own veins.
