Beginner Coming SoonHow to Identify Blood Groups: The ABO System and Rh Factor Step by Step
Why are some people called "universal donors" while others are "universal recipients"? This scientific episode takes you inside the world of the four blood groups A, B, AB, and O, explaining the scientific basis of their classification through the antigens found on the surface of red blood cells, and why distinguishing between them is a matter of life and death in blood transfusion. It also covers the laboratory tools and the practical steps of blood typing using antisera (Anti-A, Anti-B, and Anti-D) on a glass slide, and how to read the agglutination results to determine both the blood group and the Rh factor. Suitable for health sciences students and anyone interested in medical laboratory testing.
Beginner Coming SoonPlasma vs. Serum: Blood Components and How to Separate Them in the Lab
Have you ever wondered why plasma is requested for coagulation testing but serum for liver function tests? This scientific episode gives a clear introduction to the cellular and fluid components of blood, and explains the key difference between plasma and serum, the presence or absence of clotting factors such as fibrinogen, along with the clinical uses of each. It also walks through the laboratory tools and the step-by-step procedure for collecting, clotting, and centrifuging samples to separate the two fluids. Suitable for health sciences students and anyone interested in medical laboratory testing.
