Question: What blood test show mixed connective tissue disease?

Diagnosis of MCTD Blood tests are done to detect levels of antinuclear antibodies (ANA) and an antibody to ribonucleoprotein (RNP), which are present in most people who have mixed connective tissue disease.

What antibody is associated with mixed connective tissue disease?

Mixed connective tissue disease (MCTD) is a rare autoimmune disease diagnosed when a specific antibody known as anti-U1-ribonucleoprotein is present, and there are features of at least two connective tissue diseases, including systemic lupus erythematosus, systemic sclerosis, polymyositis, dermatomyositis, and ...

What does a MCTD flare feel like?

An MCTD flare is marked by an increase in symptoms that can vary in severity. These symptoms can include pain, fever, skin rash, and extreme fatigue, depending on which overlap autoimmune conditions your MCTD more closely resembles.

Which laboratory findings are typical for mixed connective tissue disease?

Laboratory Studies The initial laboratory evaluation of mixed connective tissue disease (MCTD) should include the following: Complete blood cell (CBC) count with platelets and reticulocyte count: Leukopenia, thrombocytopenia, and hemolytic anemia are common findings.

Is Mctd worse than lupus?

Mixed connective tissue disease (MCTD), a chronic disorder that has overlapping features of two or more systemic rheumatic disorders, is a relatively stable disease that is milder than systemic lupus erythematosus and systemic sclerosis, new research from Norway shows.

What is considered a high RNP antibody?

A negative antinuclear ribonucleoprotein (anti-RNP) antibody result is defined as less than 20 U based on enzyme-linked immunoassay (ELISA). A borderline result is defined as 20-25 U. A positive result is defined as more than 26 U.

What can I expect from mixed connective tissue disease?

Symptoms of MCTD (in which the fingers suddenly become very pale and tingle or become numb or blue in response to cold or emotional upset), joint inflammation (arthritis), swollen hands, muscle weakness, difficulty swallowing, heartburn, and shortness of breath.

What is the life expectancy for MCTD?

Since MCTD is comprised of a number of connective tissue disorders, there are many different possible outcomes, depending on the organs affected, the degree of inflammation, and how quickly the disease progresses. With proper treatment, 80% of people survive at least 10 years after diagnosis.

Can you have both lupus and MCTD?

Mixed connective tissue disease (MCTD) has signs and symptoms of a combination of disorders — primarily lupus, scleroderma, and polymyositis. Many people with this uncommon disease also have Sjogrens syndrome. For this reason, MCTD is sometimes called an overlap disease.

Can a positive RNP mean nothing?

Although strongly associated with connective tissue diseases, RNP antibodies are not considered a marker for any particular disease except in the following situation: when found in isolation (ie, dsDNA antibodies and Sm antibodies are not detectable), a positive result for RNP antibodies is consistent with the ...

How long can you live with mixed connective tissue disease?

Since MCTD is comprised of a number of connective tissue disorders, there are many different possible outcomes, depending on the organs affected, the degree of inflammation, and how quickly the disease progresses. With proper treatment, 80% of people survive at least 10 years after diagnosis.
