A pipette used to collected blood on my finger (lancet finger prick) came into contact with existing blood on the blood sugar testing device. this same pipette was then used to collect more of my blood off my finger ? should i be concerned ?

Depends whose blood?: If a separate sterile lancet was used for fingerprick and the pipette was only used for collection and If the blood on the device was yours and this was the 2nd test at the same time, then no problem. If it was someone else's or even yours from prior use of the device, while there is minimal risk, this is sloppy behavior and in a professional setting, should be reported to a supervisor.

Marginally: The vast majority of viruses and bacteria do not do well outside the body and do not survive long. Also the exposure is low risk as any contaminated blood was not injected in you specifically but came in contact with a small wound. I would discuss this with the practitioner and it may require testing. Also discussing hygiene issue with them in the long run.

Blood : I am surprised that this could happen . If it did Hagen I would suggest yo as the doctor to check on the phlebotomist and determine if any further testing is required. Good Luck

Bad technique: Whoever collected your blood should have used a clean pipette on the second collection, but don’t understand how your first draw of blood came into contact with existing blood on glucose testing device since test strips are good only for one use ! I think you might be confused about the process, not sure how lancet used twice, most lancets have a safety feature that only allows one stick also

No: What you described is not a cause for concern. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
