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

| Population | Interval |
|---|---|
| Ustekinumab Level | See Laboratory Report |
| Ustekinumab Ab | <2 AU/mL |

Ustekinumab and Anti-Ustekinumab Antibody, Dose ASSURE™ UST 504594
2 analytes · Serum · Fasting not stated · Turnaround 11 - 14 days
Labcorp catalog pageMethod and collection
- Method
- Electrochemiluminescence immunoassay (ECLIA)
- Collection
- Allow a minimum clotting time of 30 to 60 minutes with serum separation within 2 hours of collection. Send serum in a plastic transport tube. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
- Reference notes
- Ustekinumab drug level: <0.1 μg/mL • Result ≥0.1 μg/mL indicates detection of ustekinumab • In the presence of anti-ustekinumab antibodies, the ustekinumab drug level reflects the free, antibody-unbound fraction of ustekinumab in serum. Anti-ustekinumab antibody: <40 ng/mL • Result ≥40ng/mL indicates detection of anti-ustekinumab antibodies.

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.
