# §862.2720. Plasma oncometer for clinical use.

- (a) **Identification.** A plasma oncometer for clinical use is a device intended to measure plasma oncotic pressure, which is that portion of the total plasma osmotic pressure contributed by protein and other molecules too large to pass through a specified semipermeable membrane. Because variations in plasma oncotic pressure are indications of certain disorders, measurements of the variations are useful in the diagnosis and treatment of these disorders.
- (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 [§ 862.9](/cfr/21/862.9.md).
