Biofluids

High Quality Blood-Derived Biofluids for Research and Innovation
Our human blood-derived biofluid specimens are derived from a global network of donors, hospitals, labs, and collection sites. We provide blood and blood derivates, often used for systematic biomarker discovery and assessment.
Biofluids are sourced, collected, aliquoted and stored according to specific research needs. We recognize the critical importance of minimizing freeze/thaw cycles that could compromise the experiment.
Clinical data including demographics, treatment history, disease state, and comorbidities are often available and if so, will accompany the samples.
We work closely with our clients to deliver tailored samples from large population groups matched to your controls and research criteria. Our biobank offers an extensive and evolving collection of IRB-compliant diseased and normal samples, collected using diverse methods to suit specific research needs.

Biofluids in Inventory

US Biolab maintains an extensive repository of healthy and
disease-state biofluids in the following categories:

Saliva

Collected from IRB-compliant human donor populations across diverse demographics, our banked saliva samples represent both disease-state and healthy donors, enabling us to better serve your project. Datasets include infectious diseases, staging, collection data, pre- or post-surgical data, and more.


Matched same-donor sets paired with other biofluids and swabs are available upon request. Please inquire about custom and prospective collections to meet your needs.

Urine

Access fresh and banked urine samples from diverse global populations, ideal for diagnostic research, drug metabolization studies, and more. Our repository includes healthy and highly specific disease-state samples, fresh or banked, in the quantities you require.


Matched same-donor sets can be paired with other biofluids and swabs upon request. Please inquire about custom and prospective collections to meet your specific needs.

Sputum

Offering healthy and disease-state sputum samples from large and diverse global populations, sourced from IRB-compliant donors in domestic and international partner collection labs. Samples can be requested to represent different ethnicities, diets, and healthcare systems/protocols, enabling precise dataset modeling and more reliable conclusions.


Matched same-donor sets can be paired with other biofluids and swabs upon request. Please inquire about custom and prospective collections to meet your specific needs.

Tears

Our repository includes human tears collected from normal/healthy and disease-state IRB-compliant donors across our global network. All samples are annotated and searchable by demographic information, including gender and age. Single donor or pooled samples are available in ambient, cold, or frozen states.

Matched same-donor sets can be paired with other biofluids and swabs upon request. Please inquire about custom and prospective collections to meet your specific needs.

Swabs

Request banked or prospective swabs to meet your research needs, including cheek swabs, cervical, anal, nasal, nasopharyngeal, or any swab type. Refine your search to specify disease-state or healthy indications, ethnicities, diets, healthcare systems, and socioeconomic factors. Our repository represents a diverse range of infectious, autoimmune, & cancerous disease states, as well as healthy specimens from specific populations.


Matched same-donor sets can be paired with other biofluids and swabs upon request. Please inquire about custom and prospective sample collection to meet your specific needs.

Buffy Coats

Banked buffy coat samples include those from healthy and diseased IRB-compliant donors. Our global network offers access to samples from diverse populations and various disease states, allowing for unique tailoring to meet your study’s specific needs. All samples include related data and annotations, including longitudinal data, collection protocols, and conditions that encompass infectious diseases, cancer, autoimmune conditions, and other relevant health issues.
