SMA12, in Visit Clinic

SMA12 is a 12‑test serum metabolic panel measuring key blood chemicals — electrolytes, glucose, kidney and liver function markers, and proteins — to assess metabolic, renal and hepatic status. It’s used for routine screening, investigating symptoms, and monitoring chronic disease or treatment. Results help detect electrolyte imbalances, dehydration, kidney or liver dysfunction and metabolic disturbances, guiding further tests or clinical care.

SMA 12‑60 is a routine serum chemistry panel that measures about 12 blood analytes to assess metabolism, liver and kidney function, and electrolyte balance. It’s used for screening, diagnosis and monitoring. Typical components include glucose, urea/creatinine, sodium, potassium, chloride, bicarbonate, calcium, total protein/albumin and liver enzymes (bilirubin, alkaline phosphatase, AST/ALT). Results guide further testing or treatment.

A positive SMA can mean two different things. In blood testing, a positive smooth muscle antibody suggests an autoimmune process—often prompting further tests for autoimmune hepatitis. In genetic screening, a positive SMA indicates an SMN1 gene change: either you are a carrier (most common) or, rarely, affected. Genetic counseling and confirmatory testing are recommended; discuss results with your clinician.

A "12" blood test is a bundled panel of twelve routine laboratory tests used for general health screening and monitoring. It typically combines a complete blood count with basic metabolic measures (glucose, urea/creatinine), liver enzymes, lipid measures or electrolytes and possibly thyroid or inflammation markers. Results help detect anemia, infection, metabolic disorders, kidney or liver dysfunction, and cardiovascular risk.

SMN1 copy number: 0 copies = affected with SMA; 1 copy = carrier (though rare silent carriers can have two copies on one chromosome); 2 or more copies usually not affected but may be a carrier depending on copy distribution. SMN2 copy number predicts severity — fewer SMN2 copies means more severe disease. Positive or unclear results need confirmatory testing and genetic counseling.

Which "SMA score" do you mean — a Spinal Muscular Atrophy severity/prognosis score, a lab/clinical risk score, or something else? If you mean the SMA severity score used in spinal muscular atrophy, I can provide a 50–75 word definition; please confirm.
