#blood test

• ACTH — International acronym for adrenocorticotropic hormone (or corticotropin), a peptide hormone secreted by the anterior pituitary gland. Its primary structural role is to stimulate the production and secretion of glucocorticoid hormones (especially cortisol) by the adrenal cortex. Monitoring ACTH levels in the blood is essential for diagnosing disorders of the hypothalamo-pituitary-adrenal axis, such as Addison's disease or Cushing's syndrome.
• Agglutinated — As an adjective and participle, having undergone the process of agglutination; cells, bacteria, or particles closely united, adhered, or grouped into clusters under the action of a specific biochemical agent. In linguistics, it describes elements or words formed by welding invariable affixes. As a neuter noun, it represents the product or compact mass resulting from this structural binding process.
• Albuminemia — The presence and concentration of albumin in the blood plasma; a clinical laboratory test used for the quantitative determination of this protein fraction, serving as a fundamental indicator of nutritional status, liver synthesis function, and kidney glomerular permeability.
• Aldolase — An enzyme belonging to the lyase class that catalyzes the reversible cleavage of fructose-1,6-bisphosphate into two triose phosphates (glyceraldehyde-3-phosphate and dihydroxyacetone phosphate), a core step in the glycolytic pathway. Clinical measurements of its serum levels are utilized to diagnose acute muscle or hepatic disorders.
• Amylasemia — The presence and concentration of the amylase enzyme in the circulating blood; a clinical laboratory medical test that measures the activity of serum amylase. The evaluation of this biological constant is an essential emergency investigation in diagnosing acute abdominal syndromes, as its sudden increase (hyperamylasemia) signals damage to the pancreatic tissue or salivary glands.
• Aminoacidemia — The total concentration or presence of free amino acids in the blood stream. The structural measurement of aminoacidemia is a fundamental laboratory analysis for neonatal screening and diagnosing inborn errors of metabolism, such as phenylketonuria, or for monitoring liver and kidney function in critical pathological states.
• Antistreptolysin — The articulated form or lexical variant currently used for antistreptolysin O (ASLO); a specific antibody produced by the human immune system in response to infection with group A beta-hemolytic streptococci. This serological protein neutralizes streptolysin O (a hemolytic toxin released by the bacterium) and is quantitatively determined in laboratories via the ASLO titer to diagnose post-streptococcal complications such as acute rheumatic fever or glomerulonephritis.
• ASLO — Medical acronym for 'Antistreptolysin O', representing a specific antibody produced by the human immune system in response to a bacterial infection caused by group A beta-hemolytic streptococcus; the ASLO titer or value determined from blood serum constitutes an essential clinical indicator for diagnosing and monitoring post-streptococcal complications, such as acute rheumatic fever or glomerulonephritis.
