WTI Laboratory Services Overview

The laboratory at WTI (formerly known as EDLab) was founded in 1994 in Clearwater, Florida, USA to provide professional environmental sample testing services to the end user. This state of the art laboratory has analyzed over 250,000 environmental samples which have been collected from air, surfaces and liquids for allergens, microbes, chemicals and others.

The lab utilizes cutting-edge technologies to test various environmental samples. The results assist in understanding the quality of the environment from where the samples were collected. The unique combination of well-trained staff and a complete range of analytical technologies make the lab at WTI one of the premier environmental laboratories worldwide.

Areas of Focus Include

EDLab Microbes


Airborne materials of biological and a-biological nature such as bacteria, fungi, pollen grains, insect bio-detritus, man-made fibers, fiberglass, plant trichrome/fibers and other organic and non-organic entities are significant from health and hygiene point of view. The lab categorizes and quantifies these types of aerobiota.


Dust related allergen triggers such as dust mites, cat, cockroach, cat, dog, rat, mouse etc. are listed as a significant source of allergies and other ailments. Evaluation of submitted environmental samples is performed for qualitative and quantitative estimation of allergen load.


Aerobic, anaerobic, Thermophilic and HPC bacterial organisms can be the source of infection, contaminants and/or disease within our surroundings. Our diagnostics services help in the identification and quantification of these microorganism in environmental samples.


Biochemical agents such as allergens, mycotoxins, and endotoxin are potential sources of allergy, infection or capable of causing disease. The lab evaluates these environmental samples for the estimations of such agents.


This bacterium is known for causing infections and disease in humans. We provide non-culture, culture and PCR(DNA) based techniques for identifying and estimating these microorganisms in environmental sources such as air or water. CDC ELITE Program. NY ELAP Lab 12086.


Microscopic particulates of a-biological as well as biological nature can contaminate or pollute the indoor environment. This service examines microscopic particles found in air, surface and/or liquid samples collected from a building investigation.  


Fungi and fungal borne entities in environmental material are potential allergy, infection and disease causing agents. The lab can identify and enumerate the mold, yeast or thermophilic contamination of fungi found in environmental samples.


Additional testing and evaluation of environmental samples for potential contaminants or pollutants such as asbestos, chemicals, temperature, and humidity/moisture. The lab also has a specialized test chamber used to conduct product efficacy testing.
