🧬 DNA Testing for Identifying Dead Bodies: How It Works and Why It Matters By HealthRaise | Science Behind the Scenes In tragic incidents like plane crashes or natural disasters, identifying the deceased becomes a crucial step for both legal and emotional closure. When the body is unrecognizable due to severe trauma or decomposition, traditional methods like visual recognition or fingerprinting often fail. In such situations, DNA testing becomes the most reliable and scientific tool for identification. This is exactly what we are witnessing in the recent Air India Ahmedabad case , where authorities are using DNA tests to identify the remains of victims and match them with their relatives. 🧬 What is DNA Testing? DNA (Deoxyribonucleic Acid) is the unique genetic code found in every cell of the human body. Except for identical twins, no two individuals share the same DNA. That’s why DNA testing is considered the gold standard in forensic identification. 🔬 How is DNA Test...
Introduction Blood transfusions are life-saving, but they also carry risks if compatibility is not carefully verified. One of the most critical safety checks is crossmatching, performed in the blood bank before transfusion. In this post on Health Raise, we’ll break down how crossmatch testing is performed, its types, and its role in ensuring transfusion safety. [Blood Compatibility Chart – ABO & Rh System] 1. What is Crossmatching? Crossmatching is a laboratory procedure used to assess compatibility between a donor’s red blood cells and a recipient’s plasma. It aims to detect any immune reaction that may occur if the recipient's body recognizes the donor blood as foreign. There are two main types: Major Crossmatch – Tests recipient plasma against donor red cells. Minor Crossmatch – Tests donor plasma against recipient red cells (rarely used today due to component therapy). --- 2. Pre-Crossmatch Preparations Sample Collection: Blood is drawn from both donor and recipient, label...
