RNP Antibody details
Description
RNP (ribonucleoprotein) antibodies are autoantibodies associated most strongly with mixed connective tissue disease, a condition that shares overlapping features of lupus, scleroderma, and myositis, and high levels of RNP antibodies are actually part of the diagnostic criteria for that condition. RNP antibodies can also appear in lupus itself, sometimes without the specific overlap features of mixed connective tissue disease. It's typically tested as part of a broader autoimmune antibody panel, interpreted alongside your symptoms and other antibody results.

Single marker
RNP Antibody
$27.49
This test detects RNP antibodies. RNP antibodies are associated with mixed connective tissue disease.
- RNP Antibody An autoantibody associated with mixed connective tissue disease and, at times, lupus.
Panel
ANA + 11 Components
$1,803.99
ANA + 11 Components is a comprehensive blood test that includes the presence of antinuclear antibodies (ANAs), which are autoantibodies targeting the cell nucleus. A positive ANA screen suggests potential autoimmune activity. 11 ANA Components tests for 11 specific autoantibodies against distinct nuclear antigens, helping to identify or differentiate particular autoimmune diseases.
- Chromatin Antibodies Autoantibodies that target chromatin (DNA-protein complexes) inside your cells. Associated with lupus and other autoimmune conditions.
- Anti-Jo-1 An autoantibody associated with certain autoimmune muscle and lung conditions, including polymyositis, dermatomyositis, and antisynthetase syndrome.
- Ribosomal P Antibody An autoantibody associated with lupus, particularly linked to neuropsychiatric symptoms in some patients.
- RNP Antibody An autoantibody associated with mixed connective tissue disease and, at times, lupus.
- SS-A (Ro) Abs An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.
- SS-B (La) Abs An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.
- Centromere b antibody
- DNA (ds) Antibody
- Scleroderma Ab
- Sm Ab
- Sm/RNP Antibody
Sm Antibody and RNP Antibody
$42.49
Sm/RNP Antibodies are autoantibodies directed against components of small nuclear ribonucleoproteins. They are primarily used in the diagnosis of systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD), helping to distinguish between overlapping autoimmune conditions.
- RNP Antibody An autoantibody associated with mixed connective tissue disease and, at times, lupus.
