The results let us see which of our members have high levels of insecticide in their blood.
We measure Cholinesterase enzyme activity as a biomarker of organophosphate and carbamate insecticide exposure — higher activity indicates lower exposure risk.
| Level | Cholinesterase | Status | Action |
|---|---|---|---|
| 1 — Safe | >6,000 U/L | Minimal exposure | Normal |
| 2 — Normal | 5,100–6,000 U/L | Within normal range | Normal |
| 3 — Normal Risk | 2,900–5,100 U/L | Early exposure | Monitor |
| 4 — Medium Risk | 1,900–2,900 U/L | Moderate level | Improve |
| 5 — High Risk | <1,900 U/L | High, dangerous level | Urgent |
