A coagulation screening panel is a vital diagnostic tool. It assesses blood clotting (hemostasis) via PT, aPTT, & platelet count, revealing bleeding or clotting risks.

A D-dimer test measures a protein fragment from dissolved blood clots. It helps rule out dangerous clots like DVT or PE, but elevated levels can have other causes.

Phlebotomy involves drawing blood using a needle from a vein in the arm. To ensure patient comfort and accurate results, a skilled phlebotomist locates a vein, disinfects the area, inserts a needle, collects blood, and then removes the needle and applies pressure.
