IgG stands for immune globulin G and IgM stands for immune globulin M. Both are types of antibodies. IgM is generally produced the first time a host is exposed to an antigen. IgM will eventually decline, and then the host produces IgG, which lasts much longer. Detection of IgM indicates acute or primary infection, IgG indicates past infection or immunity.

It is important to bear in mind that common diseases, such as atrial fibrillation and stroke, occur as a result of the interplay of both environmental (including lifestyle and other health and medical conditions) and inherited risk factors. As a result, having a specific genetic risk factor for a common disease does not mean that one will necessarily develop the disease; and not having a certain risk variant does not eliminate the possibility of developing the disease.

The first documented cases of AIDS was on the 5th of June 1981, in the USA, and five people were affected with the disease. However there were reported (but not documented) cases of occurrence of HIV in 1959, But not much information was gathered on the later event. REF: FIRST OUTBREAK OF AIDS

A positive TB test means that someone has been exposed to the TB germ and follow up evaluation is needed. Once a positive TB test has been confirmed to be truly positive, there is no point in having repeat TB tests in the future. They will not hurt you, or cause disease, but will always continue to be positive. BCG vaccine (Bacille Calmette-Guerin) used in countries where TB is endemic, can decrease the severity of TB in children but will not prevent TB infection.

A positive antibody test could mean one of two things. It could mean that a person is infected with hepatitis C and is a chronic carrier. Or, it could mean that the person was infected with hepatits C but has cleared it from his or her body. An antibody test cannot tell anyone which of those two categories applies. Once infected, you will always have hepatitis C antibodies, and therefore will always test positive on a hepatitis C screening test.

No, even though a gene mutation may be present, you are not at 100% risk for developing cancer. An individual with a BRCA1 and/or BRCA2 alteration is more likely to develop cancer than an individual without an alteration. However, not every individual who has a BRCA1 and/or BRCA2 alteration will develop cancer, because genes are not the only factor affecting cancer risk.

A false positive hearing screening test result is when a baby does not have a hearing loss but the newborn does not pass the hearing screening. Hearing screening tests are not meant to diagnose hearing loss in infants. Instead, they are meant to find all infants that might have a hearing loss. Because they are not a diagnostic test, hearing screening tests sometimes misidentify infants as having a hearing loss.

You have been infected with HIV, the Human Immunodeficiency Virus, the germ which causes AIDS. It does not necessarily mean you have full blown AIDS at this time. A positive test means that the virus has entered your body through blood, semen or vaginal secretions and that you can spread HIV to others, even if you have no symptoms.

The positive result indicates that HIV-1 antibodies were detected by the laboratory analysis in the individual's blood sample that was submitted. The infected individual is capable of passing the virus to someone else. The individual must immediately seek a physician for medical advice and treatment.

Ig is an abbreviation for immunoglobulin (antibody). Five types of immunoglobulins are present in colostrum, specifically IgA, IgD, IgE, IgG, & IgM. A quick harvest ensures the highest levels of immunoglobulins and other immune factors. These energizing elements in colostrum have been scientifically proven to be anti-bacterial, anti-viral, and anti-inflammatory in nature, thereby giving a healthy boost to the immune system when consumed.

Some women have a fade-in pattern where the test will get darker for a day or two before the positive result. This generally isn't anything to worry about, and may have the benefit of a bit of advanced noticed. If you find you have a fade-in pattern, you should begin having intercourse when the fade-in pattern starts.

A positive test line means you have Stachybotrys chartarum or Aspergillus niger at the sample location, at levels detectable with this test. Although there are as yet no federal or state limits on mold or mold spores, your risk of exposure to these molds and their potential for producing harmful toxins will be greatly reduced by removing them.

A positive test indicates that there may be bleeding present in the gastrointestinal tract. Polyps, hemorrhoids, rectal fissures, or even stomach ulcers can cause bleeding that would give a positive result. The positive test result may or may not be related to cancer, so it is important to see a physician as soon as possible to determine what is causing the bleeding. Some studies suggest that only 5-10% of those with a positive test result will be diagnosed as having cancer.

In an outbreak setting, no. Previously vaccinated persons who are exposed to mumps will generally have existing, detectable serum IgG.
