Laboratory Diagnostics: Laboratory-based testing remains a cornerstone of diagnostics, encompassing a broad spectrum of assays and analyses performed on biological samples, such as blood, urine, and tissue specimens. These tests provide critical information about a patient's health status, including biochemical markers, hematological parameters, and microbiological findings. Common laboratory tests include complete blood count (CBC), blood chemistry panels, urinalysis, and microbiological cultures.
2. Imaging Diagnostics: Imaging technologies, such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound, play a vital role in visualizing anatomical structures, detecting abnormalities, and guiding medical interventions. Imaging diagnostics are used across various medical specialties, including radiology, cardiology, oncology, and neurology, to diagnose conditions ranging from fractures and tumors to cardiovascular disease and neurological disorders.
3. Molecular Diagnostics: Molecular diagnostics represent a rapidly growing field that focuses on the detection and analysis of genetic, genomic, and proteomic biomarkers associated with diseases. These tests leverage techniques such as polymerase chain reaction (PCR), next-generation sequencing (NGS), and immunoassays to identify specific nucleic acids, proteins, or metabolites indicative of disease states. Molecular diagnostics are used in oncology, infectious diseases, pharmacogenomics, and genetic testing.
4. Point-of-Care Testing (POCT): Point-of-care testing refers to diagnostic tests performed at or near the patient's location, providing rapid results that facilitate immediate clinical decision-making. POCT devices are portable, user-friendly, and often require minimal sample volumes, making them suitable for use in ambulatory settings, emergency departments, and remote healthcare settings. Common examples of POCT include blood glucose monitoring, rapid influenza tests, and pregnancy tests.
