After the needle comes out, the work isnโt finished yet.
Proper tube inversion is one of the most important steps in protecting specimen integrity.
Shaking the tube can cause hemolysis, releasing substances like potassium that may lead to inaccurate results.
On the other hand, not mixing enough can cause micro-clots, which may clog analyzers and invalidate tests like a CBC.
Thatโs why every tube has a recommended number of inversions depending on its additive.
A simple habit can make a big difference in the quality of the sample.

One full inversion = 180ยฐ turn of the wrist and back.
Sometimes accuracy is not about speed โ
itโs about doing the small steps correctly.

Do you treat tube inversion as routineโฆ or as your โquality control momentโ after every draw?
