🧬 DNA Testing for Identifying Dead Bodies: How It Works and Why It Matters

  🧬 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.

What is Hemoglobin and Why Is It Important?

What is Hemoglobin and Why Is It Important?

 Introduction:

Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. Without enough hemoglobin, your organs and tissues wouldn’t get the oxygen they need to function properly.



What Hemoglobin Does:
Hemoglobin binds to oxygen in the lungs and carries it to the tissues. It also helps carry carbon dioxide back to the lungs for exhalation.

Normal Hemoglobin Levels:

  • Men: 13.8 to 17.2 g/dL

  • Women: 12.1 to 15.1 g/dL

  • Children: 11 to 16 g/dL

Low Hemoglobin Causes:

  • Iron deficiency

  • Blood loss

  • Chronic diseases

  • Nutritional deficiencies

Symptoms of Low Hemoglobin:

  • Fatigue

  • Weakness

  • Shortness of breath

  • Pale skin

Tips to Improve Haemoglobin Naturally:

  • Eat iron-rich foods (spinach, legumes, red meat)

  • Increase vitamin C intake

  • Avoid tea/coffee right after meals

 Understanding CBC – The Complete Blood Count Test

Introduction:
A Complete Blood Count (CBC) is one of the most common blood tests. It gives a detailed picture of your overall health and helps detect a variety of disorders.

What CBC Measures:

  • RBC (Red Blood Cells): Carry oxygen

  • WBC (White Blood Cells): Fight infection

  • Platelets: Help in blood clotting

  • Hemoglobin and Hematocrit: Indicators of oxygen-carrying capacity

Why Doctors Recommend a CBC:

  • Routine health checkup

  • Diagnose anemia or infection

  • Monitor medical conditions or treatment side effects

How to Prepare:
No special preparation is needed unless your doctor advises fasting. The test involves a simple blood draw.

Reading Your CBC Report:
Your doctor will interpret the values based on your age, sex, and medical history. Don’t panic if one value is slightly out of range—it may not indicate a serious problem.
