this was a suggestion o3 made…
Here’s the shortest roadmap from idea to actual data:
| Path |
Turn-around |
Out-of-pocket |
What you learn |
Who/where |
|
RBC Glutathione (total GSH) |
5-7 days |
≈ $120 |
Biochemical proxy for antioxidant pool |
Doctor’s Data (mail-in kit) (doctorsdata.com) |
|
NanoString “Oxidative-Stress” panel (92 NRF2 targets) |
2-3 weeks |
$550-800 |
Counts for canonical NRF2/KEAP1 genes; no bio-informatics needed |
Any nCounter core (MGH, UW, MD Anderson) |
| Whole-blood RNA-seq |
3-5 weeks |
$400-500 |
Full transcriptome + custom gene-set scores |
Broad Genomics (Cambridge) or Alithea “Blood BRB-seq” (mail-in) |
DIY walk-through for the RNA-seq route
-
Grab two PAXgene® Blood RNA tubes (BD #762165; ~$15 each). They instantly freeze the expression profile for 3 d at room temp or months at –20 °C.
-
Draw 2.5 mL of venous blood into each tube (MinuteClinic, MGH Outpatient Lab, or a mobile phlebotomist). Invert ×8, let them sit ≥2 h at room temp, then freeze overnight.
-
Ship frozen tubes:
-
Local drop-off: Broad Genomics, 320 Charles St., Cambridge (fee-for-service, CAP/CLIA).
-
Mail-in: Alithea Genomics (Geneva) “Blood BRB-seq” service—globin depletion + 30 M reads included.
-
Ask for FASTQ + gene-count matrix. Run single-sample GSEA with the Hallmark NRF2 gene set; NES < –0.8 across two draws flags an under-powered oxidative-stress response.
-
Control noise: draw at the same circadian hour; fast 8 h; skip sulforaphane, caffeine, and heavy workouts for 12 h pre-draw.
If you just need a quick screen
Order the Erythrocyte Glutathione kit from Doctor’s Data. Total GSH < 3 µmol/g Hb almost always parallels depressed NRF2 target-gene expression in blood cohorts.
Bottom line:
There’s no FDA-cleared transcriptomic panel yet, but with a $30 tube, a $40 draw, and a ~$450 sequencing run you can reproduce exactly the “down-shifted NRF2/KEAP1 signature” those 2025 studies reported—and you’ll own the raw data for deeper systems-level dives later.
