Electrolytes are essential minerals in the body that carry an electric charge. They play a crucial role in maintaining fluid balance, nerve function, muscle contraction, and overall cellular activity. The primary electrolytes measured in blood tests are sodium, potassium, chloride, and bicarbonate. These ions help regulate various physiological processes and are critical for maintaining homeostasis. […]
The Thyroid-Stimulating Hormone (TSH) test is a crucial diagnostic tool used to evaluate the function of the thyroid gland. TSH, produced by the pituitary gland located at the base of the brain, plays a pivotal role in regulating the thyroid gland’s production of thyroid hormones—triiodothyronine (T3) and thyroxine (T4). These hormones are essential for maintaining […]
Introduction to the Holter Electrocardiography Test The Holter electrocardiography test, commonly known as Holter monitoring, is a continuous recording of the heart’s electrical activity over an extended period, usually 24 to 48 hours. This non-invasive diagnostic test is named after Dr. Norman Holter, who pioneered its use. Unlike a standard electrocardiogram (ECG) that provides a […]
Introduction to the Glucose Test The glucose test is a fundamental diagnostic tool used to measure the level of glucose (sugar) in the blood. Glucose is a crucial source of energy for the body’s cells, and its levels are tightly regulated by the body’s endocrine system. The test is essential in diagnosing and managing conditions […]
Introduction to the Tilt Table Test The Tilt Table Test is a diagnostic procedure used primarily to evaluate the cause of unexplained syncope (fainting) and dizziness. This test assesses how the body responds to changes in posture and gravitational stress, particularly focusing on the cardiovascular system’s ability to maintain blood pressure and heart rate when […]
Introduction to Coronary CT Angiography Coronary CT Angiography (CTA) is a non-invasive imaging technique used to visualize the coronary arteries, which supply blood to the heart muscle. This test uses computed tomography (CT) technology to create detailed images of the coronary arteries and assess their condition. By injecting a contrast dye into the bloodstream, coronary […]
Introduction to Chest X-ray A chest X-ray is a widely used diagnostic imaging tool that provides valuable information about the structures and organs within the chest cavity. It uses ionizing radiation to produce images of the chest, including the heart, lungs, ribs, and upper spine. The images obtained from a chest X-ray help healthcare providers […]
The BNP (B-type Natriuretic Peptide) and NT-proBNP (N-terminal pro b-type Natriuretic Peptide) tests are blood tests used to diagnose and manage heart failure and other cardiovascular conditions. These tests measure the levels of natriuretic peptides in the blood, which are proteins released by the heart in response to stress or damage. Elevated levels of these […]
A stress test, also known as an exercise stress test or cardiac stress test, is a diagnostic procedure used to evaluate how well the heart performs under physical stress. The test typically involves monitoring the heart’s response to exercise or medication that induces stress, providing crucial insights into cardiovascular health. The stress test is essential […]
The troponin test is a critical diagnostic tool used in the assessment of heart muscle damage. Troponin is a protein found in cardiac muscle cells, and its levels in the blood can provide valuable information about the presence and extent of heart damage. This test is particularly significant in diagnosing myocardial infarctions (heart attacks) and […]
