It should come as no surprise that, in the world of research, blood products are a foundational type of sample relied on by researchers for a wide range of studies and applications. Scientists use whole blood, plasma, serum, platelets, and other samples derived from blood every day around the world to make new breakthroughs. When using blood products, however, scientists are faced with an important question: should they use pooled or single donor samples in their research? In this blog, we’ll discuss single donor blood product samples and why they are so important in research applications around the world.
Common Blood Products
As mentioned above, there are a variety of blood products that scientists may use in their research that are all derived from blood. This includes whole blood samples, plasma, serum, complement serum, platelets, and buffy coats, among others. Blood products can be sourced from humans or animals, depending on the needs of the study, and, depending on the sample type used, can be collected and frozen for storage prior to research or is collected fresh and immediately processed and used.
Due to their nature, some blood products may typically come standard as either a single donor or pooled sample, while other products may be available as either type – what the researchers use will depend on their goals for the study. For example, human whole blood and human buffy coats are typically made available as single-donor samples. Other blood products, like plasma and serum, can be made available as either single-donor samples or as a pooled sample comprised of samples from multiple different donors combined. The type of sample the researcher uses will depend on the end goals of the experiment and how the data will be processed and applied.
Single Donor vs. Pooled Samples
As stated above, whether a researcher chooses a single donor or pooled blood product sample will depend on the end goals of the experiment and the conclusions the researcher is trying to draw from the results. Pooled samples are great if you want to draw conclusions about a general population as the sample is comprised of bio fluids from multiple individuals. In some cases, however, researchers may be studying a disease, biomarker, or other component found in blood samples that are unique to the donor individual.
Other reasons for choosing single-donor samples may include needing to test a specific trait that a single donor exhibits (such as needing a specific gender donor, a specific age, smoker vs. non-smoker, a specific disease state, etc.), needing to minimize biological variability, or wanting enhanced reproducibility. Because single-donor samples are genetically consistent, it is theoretically easier to reproduce research outcomes by using samples from the same donor each time. Further, because of the genetic consistency of single-donor samples, it is often easier to characterize samples obtained from a single donor as opposed to pooled samples. This makes single-donor samples ideal for specialized studies and other similar applications.
As an example of why researchers may want to use single-donor blood products for their research, we look at a recent study submitted to arXiv by Cornell University in January of 2026. In the study, researchers were looking to find a way to measure coagulation in real-time for patients in a medical environment. Typically, to monitor coagulation in a patient, Thromboelastography (TEG) is the traditional modality used. In this study, however, researchers used Single Donor Human Whole Blood from Innovative Research to develop an algorithm that uses AI to map small individual differences in patient samples alongside incremental amounts of clinical data about the patient to reliably make real-time predictions and diagnosis regarding the patient’s coagulation.
