**Question:** Pikes medium is used for transpo of-

A. Albumin
B. Glucose
C. Lipid emulsion
D. Leucocytes

**Core Concept:** Pikes medium is a culture medium used for the transport of cells, particularly leukocytes (white blood cells) during medical procedures like blood banking and transfusion therapy.

**Why the Correct Answer is Right:** Pikes medium is designed to preserve the viability and functionality of leucocytes during transport by maintaining optimal conditions for their survival. It is used specifically for the transport of leucocytes due to its unique composition that helps in maintaining the integrity and functionality of these cells.

**Why Each Wrong Option is Incorrect:**

A. Albumin: Albumin is a protein found in the blood that helps maintain osmotic pressure and protein transport. It is not specifically designed for transporting cells like leucocytes, and its primary function is not to preserve cell viability.
B. Glucose: While glucose is an essential energy source for cells, it is not the primary component of a transports medium as it does not directly ensure cell preservation or functionality.
C. Lipid emulsion: Lipid emulsions are used in clinical practice for fat supplementation in critically ill patients, not for cell transport.
D. Leucocytes: Leucocytes transport medium should be able to preserve cell viability and functionality, which is the case with Pikes medium, making it the correct answer.

**Clinical Pearl:** Pikes medium plays a crucial role in ensuring the safe and effective transport of leucocytes during blood banking and transfusion therapy, thereby contributing to the successful administration of transfused cells to patients and improving patient outcomes.
