list items checked in a mini physical prior to donation
- general appearance
- anemia: hgb/hct
- temperature
- blood pressure
- pulse
- weight
name the allogenic H/H requirments
- M: hgb >13 hct
- F: hgb>12.5, hct>38%
name the autologous H/H requirmens
H/H >11 or 33%
name the temperature cut off for doantions
not to exceed 37.5C or 99.5F
- helps determine bacterial infection
name the cut off for miniphysical blood pressure
less than 180/100 (FDA)
list the pulse requirments in the mini physical

what is the purpose of the DHQ
prevents donations from individuals who may be in window period of infectivity or other transmissible diseases
list health risks the DHQ attempts to address
- infectious diseases
- bacterial contamination
- cardiac strain
- birth defects
- caugulopathy
list diseases of interest for travel restrictions
- blood parasites: malaria leichmania
- virus: zika and ebola
- prions: variant CJD
when is the ‘questioning only’ approach used, and for what infectious agent
agents with defined risk but no test
- malaria, prions, ebola
when is the ‘donor testing only’ approach used, and for what infectious agent
donor test available but no questions can distinguish individual risk of infection
- WNV, chagas
when is the ‘questioning and testing’ approach used, and for what infectious agents
both ID risk of infection and effective tests
- HIV, HBV, HCV, zika, babesia, syphilus
when is the ‘use test-negative blood for specific recipients’ approach used, and for what infectious agent
high prevalence of infectious agent in donors but ID subset of recipients benefit from tested negative blood
- CMV
when is the ‘test blood component’ approach used and for what infectious agent
infectious agent not detectable in donor sample
- bacteria (platelets)
what are teh requirments for blood collection
- BP cuff inflated
- 16g needle
