Lab report names starting with S

Abbreviations

• S. Paratyphi AHWidal, Salmonella Paratyphi A (AH) TiterA Widal test titer for the flagellar (H) antigen of Salmonella Paratyphi A, a relative of the typhoid bacterium.
• S. Paratyphi BHWidal, Salmonella Paratyphi B (BH) TiterA Widal test titer for the flagellar (H) antigen of Salmonella Paratyphi B, a relative of the typhoid bacterium.
• S. Typhi HWidal, Salmonella Typhi H TiterA Widal test titer for the typhoid bacterium's H (flagellar) antigen. It can stay raised after an old infection or a vaccine.
• S. Typhi IgMSalmonella Typhi IgM (Typhoid Antibody)A blood test for IgM antibodies to the typhoid bacterium. On its own it cannot confirm typhoid fever.
• S. Typhi OWidal, Salmonella Typhi O TiterA Widal test titer for the typhoid bacterium's O antigen. One result cannot confirm or rule out typhoid fever.
• SACEthanol (Blood Alcohol)Measures how much alcohol (ethanol) is in your blood at the moment of the draw. It is a snapshot of very recent drinking, not a long-term marker.
• SaO2Oxygen Saturation, Arterial (SaO2)How much of the hemoglobin in your arterial blood is carrying oxygen, measured directly from a blood sample. Finger pulse oximeters estimate this same number.
• SARS-CoV-2 N AbSARS-CoV-2 nucleocapsid (N) antibodyChecks for antibodies to a protein inside the COVID-19 virus. A positive result can be a sign of a past infection.
• Scl-70Anti-Scl-70 (Topoisomerase I) AntibodyAntibodies against an enzyme called topoisomerase I. A positive result is linked to systemic sclerosis (scleroderma), especially the diffuse form of the disease.
• SCrCreatinineCreatinine is a muscle waste product that your kidneys filter out, so the level in your blood is one of the main tools for checking kidney function.
• SCSTSickle Cell Screen (Hemoglobin S Solubility)A quick check for hemoglobin S, the type of hemoglobin linked to sickle cell trait and sickle cell disease. It can't tell the two apart.
• sDNA-FITCologuard (Multitarget Stool DNA Test)A home stool test that looks for altered DNA and hidden blood linked to colon cancer and advanced polyps. It is a screening test, not a diagnosis.
• SeSeleniumMeasures the trace mineral selenium in your blood, which mostly reflects how much you have recently taken in from food and supplements.
• SECUrine Squamous Epithelial CellsA count of flat skin-type cells in a urine sample. A few are common. Many usually mean the sample picked up cells from the skin around the urethra.
• sEPOErythropoietin (EPO)A hormone made mostly by the kidneys that tells the bone marrow to make red blood cells. It is read alongside your hemoglobin.
• SGUrine Specific GravityHow concentrated your urine is compared with plain water. It mostly reflects how much fluid you've had and how well your kidneys balance water.
• SGOTAspartate Aminotransferase (AST)An enzyme found mainly in the liver, and also in muscle and heart. Raised blood levels can be a sign of damage to those cells.
• SGPTAlanine Aminotransferase (ALT)An enzyme made mostly in liver cells. It leaks into the blood when liver cells are irritated or damaged.
• SHBGSex Hormone-Binding Globulin (SHBG)A protein made by your liver that carries testosterone and estradiol in your blood. It helps set how much of each hormone is free to act.
• sIFEImmunofixation (IFE), SerumChecks whether a protein made by one clone of plasma cells is in your blood. If so, it names the type, such as IgG kappa.
• Sm AbAnti-Smith (Sm) AntibodyLooks for antibodies to the Smith (Sm) protein. A positive result is uncommon and is most closely linked with lupus.
• Sm-CIGF-1 (Insulin-like Growth Factor 1)A protein your liver makes in response to growth hormone. It's a steady signal of growth hormone activity, and usual levels vary a lot with age and sex.
• sNfLNeurofilament Light Chain (NfL)A protein released when nerve cells are injured. Levels rise with age, so labs use age-based ranges, and a high result does not point to one cause.
• Sp GrUrine Specific GravityHow concentrated your urine is compared with plain water. It mostly reflects how much fluid you've had and how well your kidneys balance water.
• SPESerum Protein Electrophoresis (SPEP)Lab panelSerum protein fractions with interpretation and any monoclonal spike.
• SPESPEP Interpretation (Serum Protein Electrophoresis)A written summary of your serum protein electrophoresis pattern: for example a normal pattern, a monoclonal spike, or a broad rise or fall in one protein group.
• SPEPSerum Protein Electrophoresis (SPEP)Lab panelSerum protein fractions with interpretation and any monoclonal spike.
• SPEPSPEP Interpretation (Serum Protein Electrophoresis)A written summary of your serum protein electrophoresis pattern: for example a normal pattern, a monoclonal spike, or a broad rise or fall in one protein group.
• Spike AbSARS-CoV-2 spike (S) antibodyMeasures antibodies to the virus's spike protein, which rise after COVID-19 vaccination or infection. No number is a proven sign of protection.
• Sq EpiUrine Squamous Epithelial CellsA count of flat skin-type cells in a urine sample. A few are common. Many usually mean the sample picked up cells from the skin around the urethra.
• Squam EpiUrine Squamous Epithelial CellsA count of flat skin-type cells in a urine sample. A few are common. Many usually mean the sample picked up cells from the skin around the urethra.
• SRLSirolimusThe amount of the immune-calming medicine sirolimus (rapamycin) in your blood, measured just before your next dose.
• SSAAnti-SSA/Ro AntibodyLooks for antibodies to the Ro (SSA) protein. They are common in Sjögren's disease and lupus, and they matter for pregnancy planning.
• SSBAnti-SSB/La AntibodyLooks for antibodies to La (SSB), which often appear together with anti-Ro. They are linked to Sjögren's disease and lupus and matter for pregnancy planning.
• STHGrowth Hormone (GH)A hormone from the pituitary gland that drives growth in children and helps manage body composition in adults. It is released in bursts, so one level is hard to interpret.
• SUAUric AcidUric acid is a waste product from breaking down purines. High levels can lead to gout or kidney stones in some people.
