Individual at Risk
Explanation of Condition
To calculate BMI, use this calculator:
Acceptable for PBSC if over 50kg (or 7st 12lb) and BMI less than, or equal to, 40.0.
Acceptable for BM if over 50kg (or 7st 12lb) and BMI less than, or equal to, 35.0.
Acceptable for PBSC if over 50kg (or 7st 12lb) and BMI less than, or equal to, 40.0. If BMI 40-43 discuss with MO.
Acceptable for BM if over 50kg (or 7st 12lb) and BMI less than, or equal to, 35.0. If BMI 35-40 discuss with MO.
Potential BM donors with BMI 35 to 40 should be carefully assessed for additional anaesthetic risk factors (e.g. cardiovascular, respiratory and endocrine disease). If no additional risk factors donor may at discretion of MO proceed to medical assessment when an anaesthetic opinion is mandatory before donor can be cleared to donate. The collection centre must be alerted to this additional requirement before donor is sent to medical. At medical donor must also be examined to decide whether a BMH is technically possible.
Donors outside these limits at work-up should be discussed with the medical officer who may allow them to proceed after discussion with the Medical Director.
Greater discretion may be used with overweight PBSC (rather than BM) donors, in whom an increased risk is less clear.
