Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Lumipulse® p-tau217/Beta-Amyloid 42 Ratio, Plasma 17970
| Population | Interval |
|---|---|
| ptau217 | Not Established |
| ABeta 42 | Not Established |
| ptau217/ABeta 42 Ratio | ≤0.00370 |
| Lower Risk | ≤0.00370 |
| Indeterminate Risk | 0.00371-0.00737 |
| Higher Risk | ≥0.00738 |

Verify these ranges and sources
We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
