Laboratory Section:

Core Laboratory

Glomerular Basement Membrane Antibodies (GBM), IgG

Preferred Collection Container:

SST (Serum Separator)

Also Acceptable Collection Container:

Red (No Additive)

Collection Information:

Collect blood in a SST (Serum Separator). Red (No Additive) also acceptable.

Transport Information:

Centrifuge and aliquot 1.0 mL of serum into a plastic transport vial. Send refrigerated.

Minimum Sample Volume: Minimum amount of analytical sample (serum, plasma, urine, CSF, etc.) required to perform an assay once. Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory or reflex testing. In some situations, a minimum specimen volume may result in a QNS (Quantity Not Sufficient) result, requiring a second specimen to be collected.
