Panel classifications
How PrevIQ sorts every organism into INCLUDE, WATCH, or RARE for panel design.
When you're deciding what belongs on a panel, raw rates aren't enough — you need a defensible rule that accounts for both how common an organism is and how solid the evidence is. PrevIQ applies one consistent rule to produce three buckets.
The three buckets
- INCLUDE — Clinically actionable — strong enough to put on the panel.
- WATCH — Present but lower — monitor it; revisit as more data arrives.
- RARE — Too uncommon or too little data to justify inclusion.
The exact rule
Classification depends on the prevalence rate and whether the sample is reportable (Tier A or B):
| Classification | Condition |
|---|---|
| INCLUDE | rate ≥ 5% and Tier A/B (n ≥ 30) |
| WATCH | rate ≥ 1% and Tier A/B (n ≥ 30) |
| RARE | everything else — including all Tier C, regardless of rate |
Important
Sample size overrides rate. A Tier C organism (n < 30) is always RARE, even at a 100% apparent rate, because the sample is too small to support a clinical call. This is what keeps panel recommendations defensible.
Decision flow
Is the sample reportable (Tier A/B)?
No → RARE. Yes → continue.
Is the rate ≥ 5%?
Yes → INCLUDE. No → continue.
Is the rate ≥ 1%?
Yes → WATCH. No → RARE.
Worked examples
| Organism | Rate | n | Tier | Result | Why |
|---|---|---|---|---|---|
| Organism A | 12.0% | 540 | A | INCLUDE | Reportable and ≥ 5%. |
| Organism B | 2.3% | 210 | A | WATCH | Reportable, between 1% and 5%. |
| Organism C | 0.4% | 180 | A | RARE | Reportable but below 1%. |
| Organism D | 40.0% | 12 | C | RARE | High rate, but n < 30 — not reportable. |
| Organism E | 8.0% | 65 | B | INCLUDE | Reportable (Tier B) and ≥ 5%. |
Where you'll see this
- On the Reports page, the panel recommendation view lists every organism in a syndrome with its bucket, plus a header count of INCLUDE / WATCH / RARE.
- Via the API at
/reports/panel-recommendation.
Tip
The 5% and 1% thresholds are OSPRI's standard panel-design cut points. If a specific engagement needs different thresholds, talk to your OSPRI contact — don't eyeball it from raw rates.
