Introduction

Panda blood is not type O blood. "Panda blood" refers to the RhD-negative blood type, while type O blood belongs to the ABO blood group system. "Panda blood" is a colloquial term for Rh-negative blood type, which is relatively rare within the Rh blood group system. The Rh blood group system is classified based on the presence or absence of the Rh factor on the surface of red blood cells, and is categorized into Rh-positive and Rh-negative types.

Generally speaking, panda blood is not type O blood. "Panda blood" refers to the Rh-negative blood group, while type O blood belongs to the ABO blood group system. These two are from different blood group systems. Detailed explanations are as follows:

The ABO blood group system classifies blood into types A, B, AB, and O based on the presence or absence of A and B antigens on the surface of red blood cells. The Rh blood group system, on the other hand, classifies blood based on the presence or absence of the D antigen on red blood cells. Blood containing the D antigen is classified as Rh positive, while blood lacking the D antigen is Rh negative. Since Rh-negative blood is extremely rare, occurring in a very small proportion of the population, it is referred to as "panda blood." A person can have both type O blood and Rh-negative blood simultaneously, known as O Rh-negative blood, which is even rarer among panda blood types.

Therefore, panda blood and type O blood are distinct concepts and should not be confused.

What blood type is "Panda blood"?

Under normal circumstances, "panda blood" refers to the Rh-negative blood type, a rare blood group characterized by the absence of the RhD antigen on the surface of red blood cells. Human blood group systems are primarily divided into the ABO system and the Rh system. Within the Rh blood group system, individuals are classified as either Rh-positive, meaning their red blood cells express the RhD antigen, or Rh-negative, meaning they lack the RhD antigen.

Can O blood type be transfused to AB blood type?

Under specific circumstances, individuals with type O blood can donate blood to recipients with type AB blood, but this must strictly follow blood transfusion principles and undergo necessary processing. Within the ABO blood group system, type O red blood cells lack both A and B antigens on their surface, making them theoretically suitable as a "universal donor" for red blood cell transfusions to other blood types, including type AB. This is because AB type plasma does not contain anti-A or anti-B antibodies and therefore can accept red blood cells from other blood types.

How long does it take for ABO hemolytic jaundice to resolve?

ABO hemolytic jaundice is common in newborns, especially when the mother has type O blood and the infant has type A or B blood. In such cases, if the infant's jaundice is mild and treated promptly with phototherapy and appropriate exchange transfusion, the jaundice may begin to gradually subside within 1–2 weeks after birth, and most newborns will experience complete resolution of jaundice within 2 weeks.
