FOXO4-DRI Blood Work Labs: Standard vs Research-Grade Comparison

Baseline Timing Within 30 days of start Within 7 days of first dose Research-grade timing eliminates inflammatory variability; 30-day window allows too much baseline drift CBC Differential 5-part differential 5-part + absolute counts Absolute counts required t

This page preserves a source comparison for education. It does not add a rating, recommendation or clinical judgment.

  • Baseline Timing
  • Within 30 days of start
  • Within 7 days of first dose
  • Research-grade timing eliminates inflammatory variability; 30-day window allows too much baseline drift
  • CBC Differential
  • 5-part differential
  • 5-part + absolute counts
  • Absolute counts required to detect real immune shifts vs percentage artifacts
  • Inflammatory Markers
  • hs-CRP only
  • hs-CRP + IL-6 + TNF-alpha
  • IL-6 is more senescence-specific than CRP alone; TNF-alpha optional but valuable
  • Follow-Up Schedule
  • Week 8 only
  • Weeks 4, 8, 12
  • Single timepoint misses clearance dynamics and safety window
  • Senescence Markers
  • Not included
  • p16INK4a, SA-beta-gal
  • Direct markers prove mechanism but require specialized labs
  • eGFR Threshold
  • >30 mL/min acceptable
  • >60 mL/min required
  • Research protocols exclude Stage 3+ CKD due to unpredictable peptide clearance
