An exercise in the compensation for phlebotomy

How much do I get paid per milliliter of blood I draw? How much per teaspoon? Per gallon? Here is an exercise to figure it out:

Assuming I get paid $14.36 per hour, work 8 hours per shift, perform about 20 draws per shift, draw an average of three vials per patient, and estimating that each vial ends up with about 3 mL, we can set it up this way:

(15 D/h)(8 h/1 d)(1 d/20 draws)(1 draw/3 vials)(1 vial/3 mL)

= 0.67 D/mL

(Where D = dollars, h = hours and d = number of shifts)

In other words, I get about 67 cents for every milliliter, or $2 per vial.

But I’d rather get paid by the gallon. Where 1 gal = 3 785.4 mL, we have:

(0.67 D/mL)(3 785.4 mL/gal) = 2524 D/gal

Two and a half thousand bucks per gallon, WHOO-HOO!
