Q1. What is the fundamental biological difference between PRP (1st generation) and PRF (2nd generation)?(Required)

A. PRF has more platelets but requires significantly more blood volume to produce

B. PRF uses NO anticoagulant allowing natural fibrin polymerization creating a scaffold that releases growth factors over 7-14 days vs minutes for PRP

C. PRP is superior to PRF in all measured clinical outcomes for facial aesthetics

D. PRF requires a centrifuge but PRP can be prepared manually at the chairside

Q2. i-PRF (injectable PRF) differs from standard PRF clot in which critical way?(Required)

A. i-PRF contains more fibrin and is therefore more solid and volumizing

B. i-PRF uses 700 RPM for 3 minutes (very low speed) remaining liquid for injection while richer in leukocytes and stem cells

C. i-PRF is derived from donor blood platelets not the patient's own autologous blood

D. i-PRF uses EDTA anticoagulant to prevent clotting during the centrifugation process

Q3. EZ Gel is created by combining i-PRF with which component using a specific heat protocol?(Required)

A. Hyaluronic acid filler at room temperature to create a smoother bio-filler

B. Heated albumin-rich plasma where albumin denatures under heat to form a volumizing gel matrix

C. Vitamin C solution where ascorbic acid triggers polymerization to form the gel structure

D. Platelet-poor plasma at cold temperature creating a thin biostimulatory serum

Q4. Which blood collection tube type is ABSOLUTELY required for PRF preparation?(Required)

A. EDTA tubes -- they prevent premature clotting during centrifugation

B. Citrate tubes -- standard anticoagulation for platelet preservation

C. Plain glass or silica-coated tubes -- NO anticoagulant allows natural fibrin clot formation

D. Heparin tubes -- the mildest available anticoagulant preserving platelet function

Q5. What is the critical working time after centrifugation before i-PRF begins to clot and becomes unusable?(Required)

A. 60-90 minutes -- adequate time for a full facial treatment session

B. 10-15 minutes -- ALL syringes and needles must be prepared BEFORE spinning the centrifuge

C. 30 minutes -- the standard working window for most i-PRF injectable treatments

D. 5 minutes -- must inject directly from the tube immediately after centrifugation

Q6. PRF growth factors are released over 7-14 days. How quickly does PRP release its growth factors?(Required)

A. 3-5 days -- PRP releases slightly slower than most people think

B. Within minutes -- PRP growth factors release immediately upon platelet degranulation

C. Over 48 hours -- PRP provides two days of sustained growth factor release

D. Over 30 days -- PRP actually sustains longer than PRF in clinical studies

Q7. Which growth factor in PRF is primarily responsible for stimulating new collagen synthesis by fibroblasts?(Required)

A. VEGF (vascular endothelial growth factor) -- the primary neovascularization signal

B. TGF-beta (transforming growth factor beta) -- the primary fibroblast activator for collagen I production

C. PDGF (platelet-derived growth factor) -- the primary cell proliferation signal

D. EGF (epidermal growth factor) -- the primary epidermal renewal signal

Q8. An ideal candidate for PRF facial rejuvenation is BEST described as:(Required)

A. A patient with severe volume loss who would typically require 10 or more syringes of HA filler

B. A patient with mild to moderate skin laxity volume loss or quality concerns seeking gradual biostimulation with realistic expectations

C. A patient with active infection at the injection site seeking accelerated wound healing

D. A patient who wants results equivalent to a surgical facelift but without any recovery time

Q9. During facial PRF injection, which specific technique is preferred and why?(Required)

A. Large-bore needle with a single bolus injection for maximum growth factor delivery per point

B. Fine needle 27-30G with serial puncture or retrograde linear threading for even distribution with minimal trauma

C. IV catheter cannula to maximize the flow rate of the relatively viscous i-PRF

D. Needleless injector to protect sensitive growth factors from needle-induced mechanical damage

Q10. What is the practical clinical significance of PRF being 100% autologous?(Required)

A. No informed consent is required since there is essentially no risk involved

B. Virtually zero allergy or foreign body reaction risk -- the entire product is derived from the patient's own blood

C. PRF can be used in patients with known platelet dysfunction disorders without special precautions

D. PRF can be stored in a refrigerator and reused safely across multiple patient visits

Q11. A patient on warfarin (Coumadin) requests PRF facial treatment. What is the appropriate clinical response?(Required)

A. Proceed normally -- anticoagulation therapy does not significantly affect PRF quality or outcomes

B. This is an absolute contraindication -- warfarin impairs platelet function and prevents proper fibrin clot formation essential for PRF

C. Ask the patient to skip one or two doses of warfarin before the treatment session

D. Double the centrifuge speed and time to compensate for the anticoagulant effects

Q12. What is the tear trough PRF indication, and which specific product is most appropriate for this zone?(Required)

A. Treating the undereye hollow with EZ Gel providing both gentle volume and growth factors for skin quality improvement

B. Using standard PRF membrane placed surgically in a pocket under the orbital rim

C. Injecting i-PRF intravenously for systemic skin brightening that improves the periorbital appearance

D. Applying PRF exclusively topically to the undereye -- never inject anywhere near the orbital area

Q13. PDGF (platelet-derived growth factor) plays what primary role in PRF tissue regeneration?(Required)

A. PDGF directly inactivates DHT-producing enzymes in scalp hair follicle tissue

B. PDGF stimulates cell proliferation and neovascularization -- it recruits stem cells and promotes wound healing

C. PDGF inhibits collagen overproduction to prevent post-procedure fibrosis and scarring

D. PDGF bleaches hyperpigmented skin cells during the healing process to reduce discoloration

Q14. Why is PRF specifically considered superior to PRP for facial aesthetic applications?(Required)

A. PRF contains more albumin which immediately brightens skin appearance after injection

B. PRF's fibrin scaffold provides sustained growth factor release and a 3D cell-trapping matrix creating a more durable biological effect in slowly-perfused facial tissue

C. PRF is significantly less expensive and more clinically accessible than preparing PRP

D. PRF does not require a blood draw eliminating patient anxiety about needles

Q15. Which finding discovered during pre-treatment screening would IMMEDIATELY stop the PRF procedure?(Required)

A. Patient reports drinking coffee this morning before the appointment

B. Patient has active cancer currently receiving chemotherapy or radiation treatment

C. Patient had Botox treatment in the forehead 3 weeks ago

D. Patient takes 1000 mg of Vitamin C daily and 400 IU Vitamin E

Q16. For facial PRF injection in aesthetic practice, which needle gauge is recommended?(Required)

A. 18G -- the largest bore for the fastest delivery of the PRF product

B. 27-30G -- fine gauge minimizes trauma, bruising, and patient discomfort during injection

C. 21G -- the standard phlebotomy gauge used for all PRF injection procedures

D. 34G -- ultrafine for strictly intradermal injections in delicate periorbital areas

Q17. A patient at 6 weeks post-PRF treatment series reports no visible improvement yet. What is the most appropriate response?(Required)

A. The treatment has failed -- offer a full refund and alternative treatment

B. This timeline is within the normal range -- PRF results typically onset at 4-6 weeks and continue improving over subsequent months

C. Inject double the PRF volume at the next visit to compensate for the apparent non-response

D. Add a chemical peel immediately to accelerate the visible skin quality improvement

Q18. i-PRF contains leukocytes (white blood cells). What specific clinical benefit do leukocytes contribute to PRF treatment?(Required)

A. Leukocytes cause significant inflammation and should be removed -- prefer leukocyte-poor PRP

B. Leukocytes provide antimicrobial protection and release additional cytokines including TGF-beta that enhance tissue regeneration

C. Leukocytes are completely inert in PRF and do not contribute to any clinical effects

D. Leukocytes are responsible for the volumizing effect noticed immediately after i-PRF injection

Q19. How much blood should be drawn for a standard full facial PRF treatment session?(Required)

A. 2-4 mL -- a small volume is entirely sufficient for most facial treatments

B. 20-40 mL -- this larger volume is needed for facial plus scalp hair restoration in the same session

C. 10-20 mL -- the standard blood draw volume for a complete facial PRF treatment

D. 100 mL -- a large volume is required to adequately concentrate the growth factors needed

Q20. Which statement BEST describes the appropriate patient expectation for EZ Gel as a filler alternative?(Required)

A. EZ Gel provides the identical volumizing result as 2 syringes of Juvederm Voluma

B. EZ Gel provides subtle biostimulatory volume with gradual improvement -- it is NOT a replacement for significant HA filler volume correction

C. EZ Gel is a permanent solution requiring only one treatment for lasting volumizing results
