How Efficient is your
Sampling Method?

Sample Collection is a Three Step Process:

Step 1:Location/Discovery (LD)
Probability of locating randomly distributed bacteria

Step 2: Extraction (Ex)
Probability of collecting bacteria on known location

Step 3: Elution(El)
Probability of recovering bacteria from sampling device

The product of these three steps is equal to:

Sampling Proficiency (SP):
Probability of obtaining a representative sample

The M-Vac has a much higher probability of recovering pathogens when the location of those pathogens is known and more importantly, when it is unknown.  How?  First, the M-Vac improves odds of locating and discovering existing pathogens.  Swabs, sponges, and contact plates are intended to sample small areas.  The M-Vac has the ability to sample up to 2 square feet in one sample (contiguous area or not).  Second, the M-Vac improves odds of recovering pathogens by extracting existing pathogens from the surface.  The M-Vac's vacuum pressure along with the circulating motion of a sterile solution spray produces enough commotion and suction to extract pathogens from microscopic cracks and crevices which other methods simply cannot reach.  Finally, the M-Vac is able to eliminate the need for elution.  Swabs and sponges are made to capture and retain pathogens, not elute.  With the M-Vac, elution is not needed because the bugs are already suspended in the bottle.  Considered separately and independently, these elements are extremely important.  When considered interdependently, they become even more significant.
