🧬 ADAMTS13 Activity Test — Complete Guide Key diagnostic test for thrombotic thrombocytopenic purpura (TTP)Principle · ELISA method · Reference range · Clinical significance · Interpretation points Professional guide to ADAMTS13 Activity by a medical specialist 1. What Is ADAMTS13? ADAMTS13 (A Disintegrin And Metalloprotease with ThromboSpondin type 1 motif, 13) is a plasma metalloprotease…
🩸 aPTT (Activated Partial Thromboplastin Time) — Complete Guide A core laboratory test for evaluating intrinsic & common coagulation pathways The activated Partial Thromboplastin Time (aPTT) is one of the most essential coagulation tests. It assesses whether the intrinsic and common coagulation pathways are functioning properly and is crucial in evaluating bleeding tendencies, coagulation factor…
🦟 Rapid Malaria Test (Malaria Rapid Diagnostic Test, RDT) — Complete Guide A quick, point-of-care immunochromatographic assay for malaria diagnosis Malaria is a parasitic infection caused by Plasmodium species and remains a leading global cause of febrile illness. Rapid and accurate diagnosis is essential because early treatment markedly improves outcomes. The Rapid Malaria Test (RDT)…
🩸 Methemoglobin (MetHb) Test — Complete Clinical Guide Essential diagnostic test for identifying methemoglobinemia and oxygen-carrying dysfunction Methemoglobin (MetHb) is an oxidized form of hemoglobin in which iron exists in the ferric (Fe³⁺) state instead of the normal ferrous (Fe²⁺) form. Since ferric iron cannot bind oxygen, increased MetHb levels cause a significant drop in…
🧬 Lipoprotein Lipase (LPL) Test — Complete Clinical Guide Essential enzyme test for evaluating triglyceride metabolism disorders Lipoprotein Lipase (LPL) is a key enzyme responsible for breaking down triglycerides (TG) in circulating lipoproteins. It plays a central role in lipid metabolism, and abnormalities in LPL concentration or activity can lead to severe hypertriglyceridemia, recurrent pancreatitis,…
🧪 Lipase (LIP) Test — Complete Clinical Guide The Most Specific Enzyme Marker for Acute Pancreatitis Lipase is a pancreatic enzyme responsible for breaking down dietary fats (triglycerides → fatty acids + glycerol).In clinical practice, serum lipase is the most specific and reliable biochemical marker for diagnosing acute pancreatitis, outperforming serum amylase in both diagnostic…
🧬 LAP (Leucine Aminopeptidase) Test: Complete Clinical Guide Sensitive marker for cholestasis and hepatobiliary disease Leucine Aminopeptidase (LAP) is a membrane-bound enzyme primarily found in the liver, bile ducts, pancreas, and placenta. It plays a role in cleaving N-terminal leucine from peptide chains.Clinically, LAP rises early and sensitively in conditions involving bile duct obstruction and…
🧪 LDH (Lactate Dehydrogenase) Test: A Complete Clinical Guide One of the most sensitive markers for tissue damage, hemolysis, and tumor activity Lactate Dehydrogenase (LDH) is an intracellular enzyme present in almost every tissue of the human body. When cells are damaged, LDH is released into the bloodstream, making it a highly sensitive—but nonspecific—marker of…
🟢 ICG Retention Rate (R15) Test: A Complete Guide One of the most reliable quantitative assessments of liver function The Indocyanine Green (ICG) Retention Rate at 15 minutes (R15) is one of the most widely used quantitative tests to evaluate hepatic blood flow, hepatocyte function, and biliary excretion capacity.It is especially crucial in preoperative assessment…
🧬 G6PD Test: Complete Guide to Deficiency Diagnosis and Hemolysis Risk Assessment G6PD (Glucose-6-Phosphate Dehydrogenase) deficiency is the most common inherited red blood cell enzyme disorder worldwide and a major cause of oxidative hemolysis. The G6PD test is essential for evaluating unexplained hemolytic anemia, neonatal jaundice, and drug-induced hemolysis risk—especially before prescribing oxidant medications. 🔬…
