Three ways to measure a person. One of them can change.
Your menu already touches two of them. Genetics tells a client what they’re predisposed to — fixed at conception, and it reads the same at 60 as it did at 30. Protein markers like CRP tell you what already happened — real, useful, and downstream of the thing that caused it. RNA gene expression is the layer in between: what the body is doing right now, and whether what you did changed it.
DNA · GENETICS
- Measures
- Predisposition
- Changes
- Never
- After an intervention
- Reads exactly the same
What you could be.
PROTEIN · CRP, ESR, CYTOKINES
- Measures
- What already happened
- Changes
- Downstream, and on a delay
- After an intervention
- Responds eventually, once the effect has worked its way through
What already happened.
RNA · GENE EXPRESSION
- Measures
- What the body is doing right now
- Changes
- Hours to days
- After an intervention
- Moves, and the movement is measurable
What's happening right now.
Of the three, exactly one can tell you whether your protocol worked. That isn’t a marketing claim — it’s just what the layers are.
We measure CRP too.
CRP is one of the 22 signals on the panel — read at the expression level, upstream of the protein, and in the company of 21 others. We’re not the alternative to CRP. We’re the layer above it, where the signal starts and where it’s still moving.
One of the hallmarks of aging. And the one your menu is already chasing.
Chronic, low-grade inflammation is one of the recognized hallmarks of aging. It’s a shared mechanism associated with cardiovascular disease, metabolic dysfunction, neurodegeneration, and cancer — which is why it already sits underneath most of what a longevity practice sells. The IV. The chamber. The cold. The lights. The protocol.
The problem was never that clinics don’t care about inflammation. It’s that the available tools measure it after the fact, at a single point in time, as a single number. CSP measures upstream expression signals associated with inflammatory and stress-response pathways — and measures them again after the intervention, so the change is visible.
A signal you can re-measure is a signal you can verify.
A one-time read tells you where someone is. A re-measurable read tells you whether what you did got them somewhere else. That’s the difference between a test and a tool for proving your protocol works — and it’s the backbone of the retest cycle.
What the credentialing actually covers.
CLIA-Certified
iXpressGenes is certified under CLIA to perform high-complexity clinical testing. The certification covers laboratory personnel, quality control, and proficiency testing — the federal standard for operating a clinical lab.
CAP-Accredited
The lab is accredited by the College of American Pathologists, inspected against detailed, discipline-specific checklists on a recurring cycle. It’s the credential most compliance teams look for.
The number that moves is the whole product.
Baseline at intake. Retest after the protocol. The number in between is what the client came back to see.
Baseline at intake, retest after the partner’s recommended protocol. The signal a client can watch move — and the reason they come back for the next one.
