Sourcing Human Serum & Plasma Samples in the iSpecimen Marketplace
Varied disease & analyte access
Rapid turnaround times
Research today often calls for serum or plasma samples that have been processed within two to four hours of collection. We often can deliver these specimens within hours, depending on proximity to a provider site.
Double-spun plasma
Product Collection Specifications
We offer detailed aliquoting information
For remnant collections, we procure a standard of 1 mL of serum and plasma. Outside of remnants, we can customly collect samples of any size over 0.25 mL.
Collection & processing tubes
iSpecimen can source banked orders in EDTA, ACD, LiHep tubes. For custom collections, our customers can request a collection in any tube type.

FAQs
Serum is the liquid portion of blood remaining after clotting, obtained by allowing blood to clot and then removing the clot through centrifugation. It lacks clotting factors like fibrinogen and is used for various diagnostic tests and research due to its content of proteins, electrolytes, antibodies, and hormones.
Plasma, on the other hand, is the liquid component of blood with clotting factors intact. It is obtained by collecting blood in tubes with anticoagulants to prevent clotting and then centrifugation to separate the plasma from the blood cells. Plasma is commonly used for a wide range of research studies.
iSpecimen provides access to a wide range of human serum and plasma samples to support diverse research needs. Our offerings include clinical remnant and banked serum and plasma samples, tested for specific infectious diseases.
We also provide double- and single-spun plasma in various buffers from both healthy and diseased patients. Additionally, we can collect specimens prospectively from patients with specific conditions or medical histories, ensuring you receive samples tailored to your research requirements.
Double-spun plasma offers significant advantages for research by ensuring a higher purity level compared to single-spun plasma. The additional centrifugation step further separates platelets and white blood cells that may remain after the first spin, resulting in a cleaner sample.
This increased purity is particularly beneficial for various types of assays and diagnostic tests, as it minimizes potential interferences from cellular components. Consequently, double-spun plasma is preferred by many researchers for its enhanced quality and reliability.
Yes, iSpecimen can arrange for matched sets of human serum, plasma, and other biospecimens. We can provide matched sample sets that include biofluids such as serum, plasma, and urine, along with fresh, frozen, or fixed tissue.
This capability ensures that researchers have access to comprehensive and well-coordinated sample collections that meet their specific study requirements.
For remnant collections, iSpecimen typically procures standard aliquots of 1 mL of serum and plasma. However, for custom collections, we can accommodate various sample sizes, starting from 0.25 mL and above, to meet specific research needs.
This flexibility allows us to tailor the sample volumes according to the unique requirements of each project.
iSpecimen strives to provide rapid turnaround times for serum and plasma samples. Depending on the proximity to a provider site, we can often deliver freshly collected specimens within hours of processing. For samples that need to be prospectively collected, we offer same-day and next-day collection and delivery in many cases.
Frozen samples may be immediately available from our inventory, ensuring timely access to the samples you need for your research.
Each serum and plasma sample provided through iSpecimen often comes with comprehensive and richly annotated data. This includes full product details and de-identified patient information such as demographics, diagnoses, medications, procedures, outcomes data, clinical lab test results, procedural test results (e.g., colonoscopy, mammogram, MRI), and pathology reports.
This extensive information helps ensure that researchers have all the necessary context for their studies.
