In Vitro Diagnostics: The Foundation of Modern Laboratory Medicine
Introduction
In Vitro Diagnostics (IVD) encompass tests performed on samples (such as blood, urine, or tissue) taken from the human body to detect diseases, monitor health status, and guide treatment decisions. From routine blood glucose measurements to advanced genetic assays, IVD technologies are indispensable in hospitals, clinics, and research laboratories worldwide. As healthcare shifts toward precision medicine, the IVD market continues to expand, driven by technological innovations, rising chronic disease prevalence, and demand for rapid, accurate testing.
What Is In Vitro Diagnostics?
“In vitro” means “in glass,” referring to tests conducted outside the body. IVDs include:
Clinical chemistry assays (e.g., glucose, electrolytes)
Immunoassays (e.g., hormone levels, infectious disease serology)
Molecular diagnostics (e.g., PCR, next‑generation sequencing)
Hematology tests (e.g., complete blood counts)
Microbiology cultures and susceptibility testing
Point‑of‑care (POC) tests (e.g., rapid antigen/antibody tests, glucose meters)
IVDs provide critical information on diagnosis, prognosis, therapeutic monitoring, and screening.
