Guidance at RECRUITMENT
ACCEPTABLE if donor has documented evidence of a negative validated malarial antibody test since return from malaria risk area. Otherwise the donor should be deferred until at least three years have past since return from malaria risk area.
UNACCEPTABLE if known to have positive malarial antibodies, or if less than three years have passed since return and malaria antibody status is unknown
It is not recommended for registries to routinely offer malaria antibody testing at recruitment.
Guidance at CT/WORK-UP
ACCEPTABLE if donor has documented evidence of a negative validated malarial antibody test since return from malaria risk area.
MAY BE ACCEPTABLE if found to have positive malarial antibodies, at the discretion of the requesting transplant centre.
In all cases, where a malaria risk factor is identified, the transplant centre should be told:
a) The results of antibody testing (if performed).
b) The reported malaria risk factor, including the date of last exposure/treatment cessation.
c) The interval between last exposure/treatment cessation and the date of testing (if performed), and the likely testing window period (typically 4 months for serological testing).
For positive results, the donor should be notified and counselled.
