B 3 Supplemental
The standard method of taking a blood is the use of a closed vacuum system where only then needle which is placed in the patient is accessible and causes a risk to health and safety if used inappropriately. The needle has a double end so that after the needle has been placed into the person, the blood dude is placed in a shield so that blood can be delivered by piercing the top of the tube with the second needle without any risk of Health and Safety.
If a doctor suspects that a patient is unlikely to yield the specific amount of blood that is required for a certain test, and she/he thinks that a it would be better not to use this system, then a she/he may consider using a different method.
On this occasion, the doctor may use a normal hypodermic needle and syringe them after this, changing the needle and directly injecting this into the top of blood tube.
This has serious health and safety risks. Not only does the doctor face risks of needle stick injury, she/he also is dealing with blood which, in itself, carries a significant risk of infection if inoculated into another person.
As a health care assistant, I do not participate in such activity. This is not only outside my role but also carries a higher risk of hazard to health and safety.
Another way of taking blood from an individual is via the use of a butterfly needle. This can be a lot kinder to the individual as it is easier to manipulate and less likely to move once in the vein thus less likely to cause damage to the individual.
However, there are other implications to consider. Research has shown that the use of a butterfly needle can alter or the blood cells thus increasing likelihood of invalidation of test results.
Use of a butterfly needle requires extra training, training which I have at, as yet not received. As I have not been trained to do this, I do not participate in this activity.
