Health care professionals use thyroid tests to check how well your thyroid is working and to find the cause of problems such as hyperthyroidism or hypothyroidism. The thyroid is a small, butterfly-shaped gland in the front of your neck that makes two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid hormones control how the body uses energy, so they affect nearly every organ in your body, even your heart.
HIV tests are very accurate, but no test can detect the virus immediately after infection. How soon a test can detect HIV depends on the type of test being used. There are three types of HIV tests: antibody tests, antigen/antibody tests, and nucleic acid tests (NAT).
If a person is down with fever, muscle pain, and weakness or has any other symptoms of dengue, then it is wise to get a blood test done. The only way to detect dengue is through a lab test. However, before you consider a blood test for dengue, you need to know about the different types of blood tests available because depending on the time of infection and the appearance of the symptoms, the test results may differ.
Cancer screening tests aim to find cancer before it causes symptoms and when it may be easier to treat successfully. An effective screening test is one that
A complete vitamin profile test is kind of an appropriate measuring process of the levels of different types of vitamins in the body. This test can effectively help to determine the presence of the deficiency of any specific vitamin or any such kind of abnormality in the vitamin levels in a human body. This is the major reason why a complete vitamin test is considered as one of the most essential tests.
Blood tests can give your healthcare provider a lot of information. He or she can see if certain elements in your blood are in a normal range. But in many cases, blood tests are only part of the information your healthcare provider needs to make a diagnosis of a health condition. You might need to have some other types of tests as well.
Stool (or feces) is usually thought of as nothing but waste — something to quickly flush away. But bowel movements can provide doctors with valuable information as to what's wrong when a child has a problem in the stomach, intestines, or another part of the gastrointestinal system.
Urinalysis is a series of tests on your urine, or pee. Doctors use it to check for signs of common conditions or diseases. Other names for it are urine test, urine analysis, and UA.
You may have a urinalysis as part of a routine check of your overall health, like during your yearly physical. Urinalysis is one way to find certain illnesses in their earlier stages. They include:
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.
Most people who fall sick with COVID-19 will experience mild to moderate symptoms and recover without special treatment. However, some will become seriously ill and require medical attention.
An allergy blood test measures a substance called immunoglobulin E (IgE) in your blood. IgE is an antibody that your body makes. If you have allergies, you may have more IgE in your blood than normal.
Allergies are a common, long-term condition that involves your immune system. Your immune system makes antibodies to fight off viruses, bacteria, and other things that can make you sick. With allergies, your immune system treats one or more harmless substances, such as pollen or peanuts, as a threat. To fight the "threat," your immune system makes IgE antibodies. This is what causes your allergy symptoms.
There are two types of tests for TB infection: the TB skin test and the TB blood test. A person’s health care provider should choose which TB test to use. Factors in selecting which test to use include the reason for testing, test availability, and cost. Generally, it is not recommended to test a person with both a TB skin test and a TB blood test.
Noninvasive prenatal testing (NIPT), sometimes called noninvasive prenatal screening (NIPS), is a method of determining the risk that the fetus will be born with certain genetic abnormalities. This testing analyzes small fragments of DNA that are circulating in a pregnant woman’s blood. Unlike most DNA, which is found inside a cell’s nucleus, these fragments are free-floating and not within cells, and so are called cell-free DNA (cfDNA). These small fragments usually contain fewer than 200 DNA building blocks (base pairs) and arise when cells die off and get broken down and their contents, including DNA, are released into the bloodstream.
