Platelet swirling is a noninvasive method for testing the quality of Platelet-rich plasma (PRP). Platelet swirling is caused by light diffraction due to the alignment of normal discoid shaped platelets. When these discoids align light that is diffracted creates a cloudy or swirling like appearance. ==Perform a Platelet Swirling Test== Even though this is a noninvasive test, ensure universal precautions are taken and wear the proper personal protective equipment. #Turn on a 50 to 100 watt white light source. #Hold the bag of Platelet Rich Plasma horizontally, approximately 12-30 inches away from the light. #Gently move the bag with your fingers so the PRP is in motion in front of the light. #In the thin areas of the PRP bag, observe the appearance of the unit for swirling. #Record results as seen. Results of a Platelet Swirling test are recorded as positive or extensive swirl, moderate or intermediate swirl, and absent or negative swirl. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Platelet swirling」の詳細全文を読む スポンサード リンク
