I remember the capillary tubes and…. Maybe a TB test? Something on the inside of the fore arm with multiple needles.

Lyme disease? I grew up in an area which had a lot of ticks.

Possibly for Iron test? It's one they do when I give blood and that's how they do it.

Shoot, I remember we had to do the lancet stick to ourselves in 8th grade science class.

OP's case is a finger prick blood draw. TB skin testing is injecting a small amount of tuberculin right under the skin of the forearm and measure the local skin reaction 48-72 hours later. Two completely different processes.

Yeah, I remember that. Seems to me that was also done by a nurse in school every once in a while.

It was to check for anemia. They'd do a stick, draw a little into a pipette, and drop it in, I think, distilled water. My brother had to have it done often for a couple of years when we were very young. He'd always faint and he'd get a chocolate milkshake. The one time they did me, I "fainted" and was told to stop faking.

My experience with the capillary tubes predates identification of Lyme disease.

I saw the need to dust off my Hematology textbook (now 42 years old); the old qualitative test used by the Red Cross for donation test used a copper sulfate solution after the finger or ear stick.

PCV. Packed cell volume. Per what sjtill said. I worked in an avian only veterinary clinic and we always grabbed a sample to see the PCV, the Buffy coat (white cells), etc..
It was (at that time) a quick and easy read of health.
We usually ran it in conjunction with a CBC. Knowing the types and number of blood cells can give you a decent indication of what’s going on in the system.
Of course, a chemistry really clarifies things…

It was to show you who was boss.

Same as it ever was.

Polio virus.

... or, Polio virus.

"Marco?"

"Polio!"
