In most cases, you will be eligible to donate once your results are back in the normal range. It does however depend on the cause, how long ago you had your tests and whether your testing was with your doctor or performed by Lifeblood. If you are diagnosed with low iron stores by Lifeblood on our testing and you are otherwise well with a pre-donation haemoglobin result in our acceptable range, you will be permitted to donate plasma. Call us to check your eligibility.
