Erythrocyte Sedimentation Rate (ESR) Test: Purpose, Procedure, and ResultsThe erythrocyte sedimentation rate (ESR) test, also known as the sed rate test, is a simple blood test that helps detect inflammation in your body. It measures how quickly red blood cells (erythrocytes) settle at the bottom of a test tube over one hour.When inflammation is present, certain proteins—such as fibrinogen—cause red blood cells to clump together and settle faster than normal. Therefore, a high ESR can indicate inflammation, infection, autoimmune diseases, or even some cancers.Although the ESR test cannot identify the exact cause of inflammation, it remains a valuable screening and…
C-Reactive Protein (CRP) Test: Purpose, Procedure, and Results ExplainedIntroductionThe C-reactive protein (CRP) test is a simple blood test that helps detect inflammation in the body. CRP is a substance produced by the liver in response to inflammation, infection, or tissue injury. Elevated CRP levels do not pinpoint the exact cause of inflammation but serve as a valuable indicator that something may be wrong.Doctors often use this test to diagnose or monitor conditions such as infections, autoimmune diseases, or chronic inflammatory disorders. A high-sensitivity CRP (hs-CRP) test can also help assess the risk of developing heart disease.What Is a C-Reactive Protein…
A Complete Blood Count (CBC) is one of the most common laboratory tests used to evaluate your overall health and detect a wide range of conditions — from anemia and infections to bleeding disorders, immune system problems, and even certain cancers. It’s a simple but powerful tool that provides critical insight into how well your body is functioning.What Is a Complete Blood Count?A Complete Blood Count, also known as a Full Blood Count, measures the quantity and characteristics of different blood cells circulating in your body.

Churg-Strauss Syndrome (Eosinophilic Granulomatosis With Polyangiitis – EGPA): Causes, Symptoms, and Treatment What Is Churg-Strauss Syndrome? Churg-Strauss Syndrome, medically known as Eosinophilic Granulomatosis with Polyangiitis (EGPA), is a rare autoimmune disorder characterized by inflammation of the blood vessels — a condition called vasculitis. This inflammation restricts blood flow to vital organs and tissues, potentially leading to long-term damage. A hallmark feature of Churg-Strauss Syndrome is the onset of adult asthma, often in individuals who previously had no respiratory issues. The condition may also cause nasal allergies, sinusitis, skin rashes, gastrointestinal bleeding, and numbness or pain in the limbs. Although there…
What Is Scleroderma? Early Detection for Better Disease Management Scleroderma is an autoimmune disorder in which the body produces excessive amounts of collagen — the protein responsible for skin strength and elasticity. In this condition, the immune system mistakenly attacks healthy cells and tissues, leading to inflammation and damage in various organs. The disease can manifest differently from one person to another, depending on the extent and location of tissue involvement. If left untreated, scleroderma can progress to life-threatening complications affecting the lungs, heart, or kidneys. Overview of Scleroderma Definition Scleroderma (from Greek: “skleros” meaning “hard” and “derma” meaning “skin”)…
Swollen Lips: Causes, Symptoms, and Treatment Important Note: While swollen lips are often harmless, sudden or severe swelling — especially when accompanied by swelling of the throat or difficulty breathing — can indicate a serious allergic reaction (angioedema) that requires emergency medical attention. What Is Lip Swelling? Lip swelling refers to the enlargement of one or both lips caused by inflammation or the accumulation of fluid beneath the skin. In most cases, it is a temporary and non-life-threatening condition. However, when swelling occurs as part of angioedema, it can quickly become dangerous, particularly if the airways or throat are involved.…
