Blood samples are collected using needle and syringe and having taken the blood, the syringe was left to stand before filling the blood bottles. We know this because the venesectionist who took the blood admitted doing so – they got distracted for a few minutes.
In the time the syringe was left standing, the blood settled remarkably fast, and the blood count bottle was filled last. Clearly the results are rubbish, as evidenced by the “normal” repeat sample.
This cause of spurious results should be borne in mind to avoid unnecessary and unwanted blood transfusions.
