# §866.5360. Cohn fraction IV immunological test system.

- (a) **Identification.** A Cohn fraction IV immunological test system is a device that consists of or measures that fraction of plasma proteins, predominantly alpha- and beta- globulins, used as a raw material for the production of pure alpha- or beta- globulins. Measurement of specific alpha- or beta- globulins aids in the diagnosis of many diseases, such as Wilson's disease (an inherited disease affecting the liver and brain), Tangier's disease (absence of alpha-1-lipoprotein), malnutrition, iron deficiency anemia, red blood cell disorders, and kidney disease.
- (b) **Classification.** Class I (general controls). The device is exempt from the premarket notification procedures in [subpart E of part 807](/cfr/21/part807-subpartE.md) of this chapter subject to the limitations in [§ 866.9](/cfr/21/866.9.md).
