Sm Antibody and RNP Antibody
Quest
Not offered
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.

- Smith (Sm) Antibody An autoantibody highly specific for lupus, though present in only a portion of people with the disease.
Smith (Sm) Antibody
Sm (Smith) Antibodies are highly specific autoantibodies used in the diagnosis of systemic lupus erythematosus (SLE). Their presence strongly supports an SLE diagnosis, although they are found in only a subset of patients.
- Smith (Sm) Antibody An autoantibody highly specific for lupus, though present in only a portion of people with the disease.

By analyzing a small serum sample, healthcare providers can determine if an individual has an allergic reaction to squid, which is crucial for those experiencing allergy symptoms after consuming seafood.
SS-A (Ro) Antibodies
SS-A (Ro) Antibodies are autoantibodies linked to autoimmune diseases, particularly Sjögren’s syndrome and systemic lupus erythematosus (SLE). Their presence can also be associated with neonatal lupus and congenital heart block when found in pregnant individuals.
- Sjögren's Syndrome A (SS-A/Ro) Antibody An autoantibody associated with Sjögren's syndrome and lupus; also relevant in pregnancy due to a risk of neonatal heart complications.

SS-B (La) Antibodies
SS-B (La) Antibodies are autoantibodies directed against the La protein, commonly associated with autoimmune conditions. Elevated levels are often found in Sjögren’s syndrome and systemic lupus erythematosus (SLE) and help support the diagnosis of these diseases.
- Sjögren's Syndrome B (SS-B/La) Antibody An autoantibody associated with Sjögren's syndrome and lupus, often found alongside SS-A antibodies.

Stachybotrys chartarum/atra (RGm24) IgE
Labcorp
Not offered
Stachybotrys chartarum/atra IgE Test This test checks for allergic reactions to a specific type of mold, Stachybotrys chartarum/atra, often found in water-damaged buildings. This mold grows on materials like ceiling tiles and wallboards because they contain cellulose, which the mold uses for growth.
Staphylococcal Enterotoxin A (m80) IgE
Labcorp
Not offered
This test is designed to detect specific antibodies in the blood that may indicate an allergic reaction to Staphylococcal Enterotoxin A, a common cause of food poisoning. Identifying these antibodies can help in diagnosing and managing potential allergic responses.
Stemphylium botryosum (m10) IgE
Labcorp
Not offered
This test measures the body's immune response to Stemphylium botryosum, a type of fungus that can cause allergic reactions in some people. By detecting specific IgE antibodies, this test helps identify allergies to this fungus, guiding appropriate allergy management strategies.
Steroid Panel, Comprehensive
Labcorp
Not offered
This panel identifies all major adrenal steroid hormones and facilitates the diagnosis of the four enzymatic defects associated with congenital adrenal hyperplasia (CAH). All steroids are determined in a single assay by LCMSMS using as little as 0.1 mL serum.
- Androstenedione A hormone produced by the adrenal glands and gonads that serves as a building block for testosterone and estrogen. Tested to evaluate excess androgen symptoms or adrenal disorders.
- Pregnenolone A hormone made from cholesterol that's the starting building block for all your other steroid hormones, including cortisol, DHEA, and sex hormones.
- Progesterone A hormone essential for the menstrual cycle and pregnancy. Used to confirm ovulation, evaluate fertility, and monitor early pregnancy.
