Hemoglobin, Plasma
Also known as: HGBP
Use
The Hemoglobin, Plasma test is utilized to identify increased concentration of plasma hemoglobin, which is indicative of acute intravascular destruction of erythrocytes. It is particularly useful for diagnosing conditions related to acute hemolysis rather than chronic hemolytic disorders, where it holds little clinical value.
Special Instructions
For optimal accuracy, the plasma should be separated from cells as soon as possible or within 2 hours of blood collection to prevent elevation in plasma hemoglobin levels.
Limitations
This test should not be used as a diagnostic tool for chronic hemolytic disorders as it does not provide relevant clinical value in such contexts. The measurement is specific to identifying increased hemoglobin in plasma due to acute breakdown of erythrocytes and is not indicative of chronic conditions.
