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, Quest AD-Detect® Beta-Amyloid 42/40 Ratio, Plasma 11786
| ABeta 42 | Not established | pg/mL |
|---|---|---|
| ABeta 40 | Not established | pg/mL |
| ABeta 42/40 Ratio | ≥0.170 |
Tests
Check the catalog code, specimen, method and preparation for every test that measures Beta-amyloid 40. Select up to five tests to compare them side by side.

Panels that include this biomarker
Quest AD-Detect® Beta-Amyloid 42/40 Ratio, Plasma 11786
3 analytes · Plasma · Fasting not stated · Turnaround Set up: Sun
Quest Diagnostics catalog pageMethod and collection
- Method
- Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)
- Collection
- Collect blood into a K2 EDTA Plasma tube and mix by inversion 10 times. Centrifuge to separate plasma from cells within 1 hour of collection. Carefully transfer plasma into a polypropylene tube or one of the Quest issued polypropylene pour-off/transfer tubes. Do not transfer to conical tube. If unable to centrifuge within 1 hour of collection, store tube on ice. Store frozen. Note: Quest Diagnostics does not perform this test for individuals under the age of 18. Pre-test and post-test counseling is strongly recommended.

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.
