A chromatography column is an important tool for determining what chemicals are in a given sample. You can test any material, such as food, water, air, or blood, by running it through a column containing gel or solid particles.

An analytical testing company performs non-clinical (or sometimes referred to as forensic) testing on samples sent in by you or someone else. These labs typically have specialties such as blood stain analysis, drug screening, DNA profiling, and infectious disease testing.

There are a variety of laboratories you can visit to assess your health and wellbeing. Clinical laboratories, pharmacies, nutritionists’ clinics, and oral surgeons are some of the medical facilities that may use laboratory tests to collect data about a person’s physical condition.
