What is the test of pricking fingers during physical examination?

All the testing items that use less blood generally use pricked fingers to collect blood. Such as: red blood cell, white blood cell count, platelet count, blood type determination, hemoglobin determination, etc. , collectively known as blood routine.

All the test items that use a large amount of blood should be drawn by vein. Such as erythrocyte sedimentation rate, liver function, blood lipid measurement, blood sugar measurement, etc.

Triangular needles are generally used to prick fingers, but now they are all one needle per person, which is disposable and very safe.
