BioLife Plasma donor laboratory criteria
BioLife Plasma screening includes a finger-stick blood analysis to assess anemia using hematocrit and to assess protein level. [1] BioLife states that results must be within acceptable ranges determined during the center’s medical screening process. [1]
Laboratory tests performed
- Hematocrit (anemia screening) via a small blood sample from a finger. [1]
- Protein level via a small blood sample from a finger. [1]
Where laboratory criteria are applied
- Laboratory testing occurs as part of the medical screening that includes a blood test. [1]
- After approval, BioLife uses a “mini” screening before each donation that again includes blood analysis for anemia (hematocrit) and protein level. [1]
Public numeric cutoffs for hematocrit and protein level
- BioLife does not publish numeric laboratory cutoff values for donor hematocrit or protein level on its public “who can donate” materials. [1]
Related non-laboratory donor threshold commonly checked during intake
- A minimum body weight of 110 lb is listed in BioLife’s donor eligibility checklist. [2]
Practical implication for donors with borderline lab results
- Deferral is expected when finger-stick hematocrit or protein level results are not acceptable on the day of donation under the center’s screening process. [1]
