Specimen Type

Serum


Specimen Required


Specimen Type: Serum

Container/Tube: SST or Red

Specimen Volume: 3 mL

Collection Instructions: Draw blood in a serum gel tube(s), plain red-top tube(s) is acceptable. Serum must be separated from cells within 45 minutes of venipuncture. Spin down and send 3 mL of serum frozen in a plastic vial.

To avoid delays in turnaround time when requesting multiple tests, please submit separate frozen specimens for each test requested.

 

NOTE: High serum biotin concentrations in patients taking biotin supplements may cause an interference in this

assay. Patients may be advised to stop biotin consumption at least 72 hours prior to sample collection.


Specimen Minimum Volume

1 mL (Note: This volume does not allow for repeat testing.)

Method Name

Electrochemiluminescence immunoassay (ECLIA)

Reporting Name

Golimumab and Anti-Gol Ab

Reference Values

Golimumab:

Quantitation Limit: <0.5 ug/mL

 

Results of 0.5 ug/mL or higher indicate detection of Golimumab

In the presence of serum anti-golimumab antibodies, the golimumab drug level reflects the antibody-unbound (free) fraction of golimumab in serum

 

Anti-Golimumab Antibody:

Quantitation Limit: <20 ng/mL

 

Results of 20 or higher indicate detection of anti-Golimumab antibodies.

Cautions

Failure of golimumab therapy may not always be due to the presence of anti-golimumab antibodies. Conversely, the absence of anti-golimumab antibodies does not guarantee response to treatment.
