Highlights from this day
- eight_mm — bleeding a little means you nicked a small vessel. it is not a technique failure 11:43
- eight_mm — abdomen two inches out from the navel, avoiding anything that has been injected in the last month the difference between 29G and 31G is real but small. the difference… 13:34
- VialBot — Inter-lab diff for lot KP-0925: 99% vs 98.1%. Within expected range. 13:35
- amsterdam_aliquot — do not reuse pins. it is not about sterility so much as the tip being blunt after one pass 13:54
warming the vial in your hand for a minute is the cheapest comfort improvement there is

welts at the site are usually a mild local reaction and rotation sorts it
Testing queue: 5 submissions open, 113 awaiting dispatch.
i have eight sites and an eight week rotation. it is written on the fridge, your mileage will differ
fresh pin
rotate
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
do you count to five before withdrawing
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
90 degrees or 45
mark it down
does the injection site matter for how quickly it hits

technique probably
coming back to this a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
do you change the pin between drawing up and injecting
genuine question let the alcohol dry. that is ninety percent of "my injections sting"
dont recap
