Education varies depending upon employer, location and type of inspection. According to the BLS, a degree in construction engineering technology is applicable towards the career. Licensing requirements also vary by jurisdiction; as of 2015, 36 states had regulations for home inspectors.
If you are pregnant, then the blood pregnancy test is usually positive within 3-4 days after implantation or about 10-11 days after fertilization and ovulation. The urine pregnancy test is positive several days after the blood test becomes positive.
A blood test will show if you are pregnant or not 7 days following conception. I believe that a blood test can show resolts two weeks after conception. And yes they will detect it before a home test will. A blood test can detect as early as 4 weeks and a urine test as early as 6 weeks. As early as 10 days after conception, definitely by the time you've missed your period.
