A black mold test does not really have any significant differences from other testing which may identify one mold species from another. However, there are many basic testing services offered in the marketplace which do not always provide the facts regarding specific mold identification. As a result, basic testing kits do not always provide the information needed to make an informed decision.

Black mold is an industry term which generally applies to one type of species known as stachybotrys chartarum. Some people do refer to any species as "black mold" which may lead to confusion since most all mold types will turn a dark brown or black color when they die. Stachybotrys has received much press over the past few years because it is considered to be a dangerous pathological species compared to others which may also be found in the indoor environment.

Mold Contamination Standards
Unfortunately, there are no standards which have been established for mold in the indoor residential environment. Since there are no real indoor standards, testing can cause a false sense of urgency or relief. Testing the indoor air for the presence of mold requires complex equipment which should be operated by experienced professionals and is the most accurate method to affirm that a residence is free of a dangerous mold. However, many mold testing products and services are sold as kits which may only identify a certain mold without quantifying the amount of that particular species.

All Homes Have Some Mold
Finding an indoor residential environment which is completely mold-free is virtually impossible. This is due to the fact that the outdoor environment has many fungal species lurking just outside the door or window which can come inside each time they are opened. Most central ventilation and air-conditioning systems create a negative pressure in the structure when they are operating and can act like a vacuum pulling in particles from the outdoor environment.

Mold Problems Require Professional Help
Just because a particular mold species has been identified in the indoor environment does not always indicate there is a mold contamination. Identifying that an indoor mold contamination is present requires an assessment which looks at such factors as relative humidity, the indoor location of the mold species, the type of mold species and the amount of mold found. While these are the primary factors which help a mold professional determine a mold problem, there may be others according to the conditions observed.

In summary, mold like other indoor contaminants require a full assessment of all factors present before making a determination of a remedial need. Having a residence which is proven to be free of major mold problems or that may have a mold problem should be left up to a professional who can help interpret the findings for your individual situation. In addition, it is paramount to choose a professional contractor for mold removal to assure the problem will not re-occur.
