Sometimes, yes. Depending on your medical history, medications or specific concerns, a blood test may be recommended before undergoing PRP therapy. Blood tests help assess platelet count, iron levels, inflammatory markers and overall suitability for PRP. If platelet levels are low or iron deficiency is present, PRP may not deliver its full potential benefits. A blood test can also help rule out underlying conditions that may interfere with healing or response to treatment. While not mandatory for all patients, it is a valuable step for those with medical conditions or chronic illnesses. Your clinician will advise you based on your situation.
