Tests
An immunoglobulins blood test measures the amount of immunoglobulins in your blood. Immunoglobulins are also called antibodies. Antibodies are proteins that your immune system makes to fight germs , such as viruses and bacteria . Your body makes different kinds of antibodies to fight germs in different parts of the body and at different stages of an infection.
Tests
Laboratory test involving interaction of antigens with specific antibodies.
Tests
Lyme disease is an infection caused by bacteria you get from tick bites . Lyme disease tests look for signs of infection in a sample of your blood or cerebrospinal fluid (CSF). CSF is a clear liquid that flows in and around your brain and spinal cord. The test checks your sample for antibodies that your immune system makes to fight the bacteria that cause Lyme disease.
Tests
A proprietary serology assay that can be used to measure IgG antibodies against the SARS-CoV-2 nucleocapsid protein (N).
Tests
A proprietary serology assay that can be used to measure IgM antibodies against the SARS-CoV-2 nucleocapsid protein (N).
Tests
A proprietary serology assay that can be used to measure IgG antibodies against the SARS-CoV-2 S1 spike receptor-binding domain (RBD).
Tests
A proprietary serology assay that can be used to measure IgA antibodies against the SARS-CoV-2 spike protein (S).
Tests
Myasthenia gravis (MG) tests are used to diagnose MG, a chronic (long-lasting) autoimmune disease that causes weakness in muscles throughout your body. In autoimmune diseases, your immune system mistakenly attacks the healthy cells of your organs and tissues. If you have MG, your immune system makes antibodies that block or change the connection between your nerves and muscles.
Tests
RSV stands for respiratory syncytial virus. It is a viral infection that affects the respiratory tract. Your respiratory tract includes your lungs, nose, and throat. RSV testing checks a fluid sample from your nose to see if the virus is in your body and causing symptoms of a respiratory infection.
Tests
A test designed to detect the presence of Rickettsia conorii antibodies in serum.
Tests
Syphilis tests generally look for certain antibodies in your blood. Antibodies are proteins that your immune system makes when it finds harmful substances in your body. In this case, the harmful substance is the bacterium that causes syphilis , one of the most common sexually transmitted infections (STIs.)
Tests
A Zika virus test looks for signs of the Zika infection in your blood or urine. Zika is a type of flavivirus, as is dengue fever and West Nile . Like those viral infections , Zika is usually spread by mosquitoes , especially in areas with tropical climates, such as parts of Central and South America, Africa, Mexico, and islands in the Caribbean and Pacific. Because Zika can enter bodily fluids such as blood, urine (pee), and semen, it can also spread through sex with an infected person or from a pregnant woman to her fetus.
