IVD领域常用英语

In vitro diagnostic (IVD) tests are essential in the field of healthcare. They help diagnose diseases, monitor treatment progress, and ensure patient safety. Here are some common English terms used in the IVD industry:



1. Immunoassay: An immunoassay is a test that uses antibodies to detect the presence of a specific substance in a patient's sample, such as a blood or urine sample.



2. PCR: Polymerase chain reaction (PCR) is a technique used to amplify DNA sequences, making it easier to detect genetic material from pathogens.



3. ELISA: Enzyme-linked immunosorbent assay (ELISA) is a type of immunoassay that uses enzymes to amplify the signal of a target substance.



4. Lateral flow: A lateral flow test is a simple diagnostic test that uses a paper strip to detect the presence of a specific substance in a patient's sample.



5. Sensitivity: Sensitivity refers to the ability of a test to correctly identify true positive results, or the rate of true positives in a population.



6. Specificity: Specificity refers to the ability of a test to correctly identify true negative results, or the rate of true negatives in a population.



7. Point-of-care testing (POCT): Point-of-care testing refers to diagnostic tests that can be performed at the patient's location, such as a doctor's office or home.



8. Quality control (QC): Quality control refers to the measures taken to ensure that diagnostic tests are accurate and reliable.



9. Reference range: A reference range is the range of values that is considered normal for a particular diagnostic test.



10. False positive/negative: A false positive test result occurs when a patient's sample is incorrectly identified as positive for a disease or condition. A false negative test result occurs when a patient's sample is incorrectly identified as negative for a disease or condition.



In conclusion, understanding these common terms used in the IVD industry is essential for healthcare professionals, researchers, and patients. It ensures accurate diagnosis, better patient outcomes, and improved overall healthcare quality.
