How are tests done?
Most commonly, blood is drawn and sent to a lab, where scientists isolate DNA from cells in your blood and use it to perform the genetic test. Sometimes a lab can use skin cells scraped from the inside of your cheek or collected in a special mouthwash. Your doctor can tell you what type of sample the lab needs.

How long will it take to get my results? This varies depending on the type of test, which laboratory is doing the test and what gene/disease is being tested. Results of some tests are available in less than a week while others take several months. Most of the time, results are available within 4 to 6 weeks or less. My test came back positive. Does that mean I will get the disease? Not necessarily. As with any test, there is always a chance for a “false positive,” meaning that even though the results appear positive, the results do not portray the true picture and the results should have been negative. This is an important risk to think about before getting tested. Some genetic c
There are three types of tests: • Air • Water • Pressure Each test requires a minimum and a maximum level of acceptance. • Air: Levels 1, 2, 3 Level 3 is the min and max acceptable level on the market. • Water: Levels 1, 2, 3, 4, 5, 6, 7 This is the most important of all three tests. The minimum required on the market is level 3. • Pressure: Levels 1, 2, 3, 4, 5 Level 3 is the minimum required on the market. A window rated A3, B3 and C3 is considered an acceptable product in the market. A window with an A3, B7, and C5 rating is considered to be one the best windows in the North-American market.
