There is a condition called Latent TB, where the bacteria live in the body but remain "asleep," causing no symptoms and no transmission. However, this silent guest can wake up and become Active TB when the immune system drops. To detect this hidden threat accurately, the IGRA Test (Interferon-Gamma Release Assay) is the gold standard. IGRA is an advanced blood test that measures the immune system's response to TB bacteria...

To get a clear picture of what is happening inside the chest cavity, doctors usually prescribe a Chest X-Ray, also known as a Thorax Photo. This is the most common diagnostic imaging test used in modern medicine. A chest X-ray uses a small dose of ionizing radiation to produce images of the structures inside the chest. Think of it as a transparent camera shot that reveals the condition of the lungs, heart, airways, blood vessel...

Urea Test, The Indicator of Kidney Function The kidneys work nonstop as the body’s natural filtration system. One of their main tasks is to remove “waste” produced from protein metabolism, known as urea. To determine whether this filter is still functioning optimally or starting to struggle, the Urea test or Blood Urea Nitrogen (BUN) test is key. In this edition of Labpedia, let’s understand that urea is formed in the liver and should be excreted through urine. If test results show high ur...

Content: Ever had a small cut that just wouldn't stop bleeding? Or woke up with mysterious bruises without bumping into anything? These could be red flags indicating an issue with the body's blood clotting system (coagulation). The medical way to check this is through PT (Prothrombin Time) and APTT (Activated Partial Thromboplastin Time) tests. In this edition of Labpedia, let's break it down. The body has a complex mechanism to clot blood and prevent excessive bleeding. PT evaluates the extr...
