Organ pipes are generally made out of either metal or wood. Very rarely, glass, porcelain, plastic, paper, Papier-mÃ¢chÃ©, or even stone pipes may be seen. A historical organ in the Philippines has pipes made exclusively of bamboo. Metal pipes are usually made of lead; for increased rigidity it is alloyed with tin along with trace amounts of antimony and copper.
Lyme Disease IgM antibodies usually appear 1-2 weeks after an initial exposure and return to normal after about 6 to 8 weeks. IgG antibodies are detectable in most people 4-6 weeks after exposure but may be detectable sooner in some people. IgG antibodies may persist indefinitely.
The EBV antibody test can also detect the type of antibodies (immunoglobulins) present in the blood. The type of antibody shows whether the infection is recent or old. The antibody IgM is only found during the active phase of mono. The antibody IgG can be found later, when you are starting to get better. The results of an EBV antibody test are usually ready within 3 days.
