Is there a consensus on backfilling syringes (2-3) at a time and letting them sit for up to a week? My concern is sterility (if that is a word) and if it is ok to leave the test in the plastic syringe for that time period. I tried it once with a mid week injection and it was faster to just pull the syringe and inject, needle is sharper, and fewer punctures of vial.
Any advice or input? Thanks.
