What is Typhoid? ‘What is Typhoid?’ Typhoid or Typhoid Fever is an infection that is spread due to ingesting contaminated food or water. Typhoid is a bacterial infection, and it tends to affect more than one organ. Once it enters the bloodstream, it affects the gastrointestinal tract, including the liver, spleen, and muscles. In some cases, the liver and spleen also tend to swell up. The symptoms of typhoid are very generic; they include weakness, stomach pain, headache, diarrhoea or constipation, loss of appetite, coughing and vomiting. Salmonella enterica serotype Typhi bacteria cause typhoid. This bacteria can be detected via testing blood samples, stool or urine samples of the affected individual. These tests do not detect this bacteria the first time, so it may require a series of tests to get the result. Whereas, in the case of a bone marrow culture test, the results are most accurate. However, this method is not the most suitable as it is invasive and not feasible. Hence, not practised that often. Various parameters are examined when testing for typhoid, and two main parameters that are tested are Typhoid IgG and IgM antibodies. What does typhoid IgG Mean? Typhoid IgG stands for immunoglobulin G. IgG antibodies are always present to tackle the infection. It multiplies and fights any harmful foreign substance that enters the body. When there are not appropriate amounts of IgG present, one is more likely to get infections. The ideal range, which is considered normal, ...

The Difference Between Tests for COVID-19 (Coronavirus) COVID-19 (Coronavirus) Molecular (Swab) Test This test uses a long swab to collect material, including physical pieces of coronavirus, from the back of the nose where it meets the throat. A positive result indicates that viral genetic material is present, but it does not indicate that bacterial or other infections also are present. A negative result indicates that the SARS-CoV2 virus that causes the COVID-19 disease was not found. It is possible to have a very low level of the virus in the body with a negative test result. This test is needed to identify the presence of the SARS-CoV-2 virus that causes the COVID-19 disease. COVID-19 (Coronavirus) Antibody (Serology) Tests Nucleocapsid Protein IgG Antibody Test This is a blood test. It is designed to detect IgG antibodies specific for nucleocapsid protein of the coronavirus that causes the disease called COVID-19. Antibodies are proteins produced by the immune system in response to an infection and are specific to that particular infection. They are found in the liquid part of blood specimens, which is called serum or plasma. Nucleocapsid Protein and IgG Spike Protein IgG antibody tests may either be ordered together or separately. Having the nucleocapsid protein antibody test is helpful if: • Your health care provider believes you may have been exposed to the coronavirus which causes COVID-19 based on your current or previous signs and symptoms (e.g., fever, cough, di...

IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been infected or that you have recently been vaccinated and your immune system has started responding to the vaccination and that your immune system has started responding to the virus. What is the purpose of IgM? IgM not only serves as the first line of host defense against infections but also plays an important role in immune regulation and immunological tolerance. For many years, IgM is thought to function by binding to antigen and activating complement system. Table of Contents • • • Does IgM mean active infection? When IgM antibodies are present, they can indicate that a patient has an active or recent infection with SARS- CoV-2. What does it mean if your IgG is positive? The presence of IgG suggests that the infection happened weeks to months in the past. It also suggests that you may no longer be infectious. IgG indicates that you may have some immunity to the virus, though you may not. How long do IgM antibodies last Covid? IgA and IgM antibodies were short-lived against the spike protein that crowns SARS-CoV-2, vanishing within about two months. The good news is that the longer-lasting IgG antibodies persisted in these same patients for up to four months, which is as long as the researchers were able to look. What comes first IgG or IgM? IgM antibody appears first, followed by IgA on mucosal surfaces or IgG in the serum. The IgG ant...

Swab Testing (testing for current infection) A nurse collects a nasal swab to look for active infection with the novel coronavirus (SARS-CoV-2, the virus that causes COVID-19). The results will be one of the following: • Detected , meaning most likely you DO currently have active COVID-19 • Not detected, meaning most likely you DO NOT currently have active COVID-19 • Inconclusive , meaning the test was unable to determine if you have active COVID-19 • Invalid, meaning there was something wrong with the nasal swab sample, so testing for active COVID-19 was not possible • Test not performed, the COVID-19 test was not done. This could be because no sample was collected, or for another reason If it is most likely that you HAVE a current active COVID-19 infection, you can give the virus to others. We recommend that you stay home and follow all CDC guidance ( If it is most likely that you DO NOT HAVE a current active COVID-19 infection, if you develop symptoms, you should monitor symptoms and seek medical advice about staying home and if you need to get tested again. If you don’t have symptoms, you should get tested again only if your medical provider and/or workplace tells you to. Antibody Testing (testing for past infection with the virus) The nurse also collects a blood sample to test for antibodies, to look for evidence of past infection with the novel coronavirus. Antibodies are proteins that are produced by the immune system in response to a specific infection. Your blood ...

This test checks the amount of certain Antibodies are Some conditions cause your body to make too many or too few immunoglobulins. Having too few immunoglobulins in your Types of Immunoglobulin Your body makes a few different types of immunoglobulin antibodies, including these: Immunoglobulin A: IgA antibodies are found in the mucous membranes of the Immunoglobulin G: IgG is the most common type of antibody in your blood and other body fluids. These antibodies protect you against infection by "remembering" which germs you've been exposed to before. If those germs come back, your Immunoglobulin M: Your body makes IgM antibodies when you are first infected with new bacteria or other germs. They are your body's first line of defense against infections. When your body senses an invader, your IgM level will rise for a short time. It will then begin to drop as your IgG level kicks in and increases to protect you long-term. Immunoglobulin E: Your body makes IgE antibodies when it overreacts to substances that aren't harmful, such as Why You Might Need This Test Your doctor might order an immunoglobulin test if you get a lot of infections -- especially infections of the They may also order the test if you have: • • Unexplained weight loss • • • • Sickness after traveling • How the Test is Done Doctors often measure IgA, IgG, and IgM together to get a snapshot of your immune function. A lab tech will usually take a sample of your blood by inserting a needle into a vein in your arm....
