About Serum


We offer serum samples from normal healthy donors and those with various autoimmune and other diseases.

Normal Donors

Our normal donors are healthy individuals who may take some medications such as low dose aspirin, birth control pills, omeprazole, or anti-depressants, but are not in the care of a physician. Some donors may also have allergies, which are noted in the Certificate of Analysis when present. Serum from these donors is especially useful as a normal control or for understanding the effect of different sample types on a new assay.

Rheumatoid Arthritis

Rheumatoid arthritis patients often have autoantibodies in their serum. Rheumatoid factor is the classic example, but antibodies to citrullinated protein are now considered reliable biomarkers for rheumatoid arthritis. Our serum samples can be used for study of these antibodies or for development of assays.

Systemic Lupus Erythematosus (SLE)

SLE is an autoimmune disease characterized by the presence of antibodies that bind double stranded DNA and other nuclear antigens. Serum from these donors is useful because of these antibodies. The presence of these antibodies can also create false positives or false negatives in diagnostic tests, so samples from SLE patients can test the robustness of new assays.

Type II Diabetes

The incidence of this metabolic disorder is on the rise and a better understanding is needed. We have noted the HgbA1C levels for all of the type II diabetes serum samples in our bank.

Other Diseases

We have serum samples from individuals with a variety of disease such as Ankylosing Spondylitis, Sjögren’s Syndrome, Mixed Connective Tissue Disease (MCTD) and Celiac Disease. Antibody values and the medications being taken are included in the Certificate of Analysis for each lot.
