Analysis of 8 igg autoantibodies and 2 cell-bound complement activation products associated with autoimmune disease, using enzyme-linked immunosorbent immunoassay (elisa), flow cytometry and indirect immunofluorescence in serum specimen or plasma and whole

The "Aids sle alys 8 igg autoant" test is a diagnostic procedure to detect autoimmune diseases such as Systemic Lupus Erythematosus (SLE). It involves analyzing your blood for 8 types of autoantibodies (proteins your body may mistakenly produce against its own cells). The results aid in diagnosis and treatment planning.

This service was performed 13,588 times for 13,587 patients

Analysis of substance using immunoassay technique, multiple step method

This procedure involves the use of an immunoassay, a highly sensitive technique, to detect and measure substances in your body. It involves multiple steps and is commonly used in diagnosing and monitoring various health conditions.

This service was performed 25,721 times for 14,852 patients

Analysis using chemiluminescent technique (light and chemical )reaction

Chemiluminescent analysis is a lab test that uses a special reaction between certain chemicals to produce light. This light is then measured to help understand specific elements in a sample. It is a non-invasive and highly accurate testing method.

This service was performed 5,506 times for 2,710 patients

Antineutrophil cytoplasmic antibody titer

The Antineutrophil Cytoplasmic Antibody (ANCA) titer is a blood test that helps diagnose autoimmune diseases. It measures the level of ANCA antibodies in your blood, which can indicate conditions like vasculitis, where your immune system mistakenly attacks your own blood vessels.

This service was performed 2,776 times for 2,724 patients

Beta 2 glycoprotein 1 antibody (autoantibody) measurement

The Beta 2 Glycoprotein 1 Antibody measurement is a blood test that helps detect certain autoantibodies. These autoantibodies can cause blood clots or pregnancy complications. The test aids in diagnosing conditions like antiphospholipid syndrome.

This service was performed 34,663 times for 14,747 patients

Cardiolipin antibody (tissue antibody) measurement

Cardiolipin antibody measurement is a blood test that checks for certain antibodies in your body. These antibodies might be present if you have an autoimmune disease, a condition where your body's immune system mistakenly attacks healthy cells. This test helps in diagnosing and managing such conditions.

This service was performed 34,795 times for 14,743 patients

Flow cytometry technique for dna or cell analysis, each additional marker

Flow cytometry is a technique that helps analyze the physical and chemical characteristics of cells or particles. When an additional marker is used, it aids in identifying specific cell types or stages of disease. This helps in precise diagnosis and treatment planning.

This service was performed 227 times for 198 patients

Flow cytometry technique for dna or cell analysis, first marker

Flow cytometry is a technique used to examine microscopic particles, like cells or DNA. It employs a beam of light to detect and measure physical and chemical characteristics of these particles. The 'first marker' refers to a specific characteristic or feature used to identify a particular cell or particle.

This service was performed 563 times for 466 patients

Measurement of antibody for assessment of autoimmune disorder, any method

This procedure measures the level of specific antibodies in your body to assess if you have an autoimmune disorder. Antibodies are proteins your immune system produces. In autoimmune disorders, these antibodies mistakenly attack your own cells. This test helps identify such conditions.

This service was performed 62,283 times for 14,610 patients

Measurement of antibody for assessment of autoimmune disorder, titer

This test measures the level of specific antibodies in your blood, which can help in the diagnosis of autoimmune disorders. A titer refers to the concentration of antibodies. High titers can indicate an active autoimmune disease.

This service was performed 337 times for 337 patients

Measurement of antibody for rheumatoid arthritis assessment

This procedure measures the level of certain antibodies in your blood. These antibodies can be higher in people with rheumatoid arthritis, a condition causing joint inflammation. The test helps in diagnosing or monitoring the disease.

This service was performed 334 times for 334 patients

Measurement of complement (immune system proteins), antigen,

The measurement of complement (immune system proteins) and antigen is a blood test. It helps to assess how your immune system is functioning. Complement proteins play a role in your body's immune response, and antigens trigger this response. This test helps in diagnosing and monitoring certain diseases.

This service was performed 8,005 times for 3,751 patients

Measurement of dna antibody, native or double stranded

The measurement of DNA antibody, native or double stranded, is a blood test that helps detect autoimmune disorders, such as lupus. It identifies if your body is producing antibodies against its own DNA, which can indicate an overactive immune response.

This service was performed 3,574 times for 3,332 patients

Measurement of hydroxychloroquine

Measurement of hydroxychloroquine is a test that checks the level of a medication called hydroxychloroquine in your body. This is to ensure that the amount is safe and effective for treating conditions like arthritis or lupus. It involves a simple blood test.

This service was performed 1,165 times for 1,014 patients

Measurement of methotrexate

Measurement of methotrexate is a blood test that determines the amount of methotrexate, a medication often used in treatment for certain types of cancer or autoimmune diseases, in your body. This helps to ensure the dosage is effective and safe.

This service was performed 645 times for 575 patients

Measurement of substance using immunoassay technique

An immunoassay technique is a laboratory method used to detect and measure specific substances in the body. This is done by using antibodies that can recognize and bind to these substances. The results can help in diagnosing and monitoring various health conditions.
