Haptoglobin itself can be an antioxidant protein, but not all sorts of haptoglobin are equally good at carrying out antioxidant activity. For instance, individuals who carry the haptoglobin-2 type have high levels of iron in their blood also. Iron can convert antioxidants like vitamin C into pro-oxidants that actually raise the degradation of good cholesterol. The combination of high iron and high blood sugar boosts oxidation in a similar way. This additional problem will help explain why supplement therapy creates such significant setbacks in diabetics with atherosclerosis, Levy says.Barrier 3. Test producers perceive that there is an inconsistent and unclear regulatory pathway because of their submissions. Manufacturers have faced uncertainty and/or inconsistency in the overview of device submissions, in enforcement discretion, in device classification [510, 510 de novo, PMA, ASR, etc.], in requirements for acceptable analytical and clinical validations, and in requirements changing from the time of pre-IDE meetings through mid-trial. ‘IVD test manufacturers must after that function within this uncertain regulatory environment, that makes it difficult to anticipate regulatory requirements and properly amend their business versions,’ said Dr. Sobel.
