What is a biological sample?

It is any biological material or substance from a human being. They can be organs, cells, tissues, or body fluids such as urine, saliva, blood, cerebrospinal fluid, among others.


During an investigation process, biological samples are fundamental in the evaluation and analysis of a disease. In addition, they are indispensable to understand their physiology in the human body.



The study of the collected samples guides researchers in a more precise way about the progress of a medical condition in its early stages, allowing the design of more effective treatments.


This process is carried out once the procedure is explained to the patient and they sign the consent form. In the case of blood samples, weight, age, and physical condition are always assessed prior to sample collection.


What is the purpose of collecting samples?


Commonly, the purpose of collecting a biological sample in clinical research is to search for and identify better therapies for medical conditions with no immediate cure. Some of its other functions are:

  • Identify and validate ways to deliver drugs or agents to specific cells.

  • Grouping patients to determine what treatment is appropriate for different stages of a disease.

  • Develop screening tests to detect biomarkers.

Some common doubts about the process.


“What is the handling of a biological sample?”


The samples collected in the extraction room, depending on the type of analysis and the study protocol, will be divided or not into different parts according to different work areas.


“After how long is the sample discarded?”


The tubes that will not be used in the laboratory, are discarded in waste containers or bulky fluids suitable for medical-biological material.


If you wish to participate and doubts still persist, you can contact us at the phone numbers provided at the end of the article. Continue until the end:



It's time to take the initiative to volunteer!


If you do not have previous experience as a biological sample volunteer, the procedure lasts approximately between 10 to 25 minutes. Samples are collected in our laboratory according to the study criteria, so it is important to contact our physicians beforehand to evaluate the participant's profile.


Each volunteer receives a compensation of $50.


If you qualify for any of these studies, contact us to start the process.
