John Kang WebMD Exposes and Corrects Misconceptions About Blood Donation

Share Article

There are beliefs about blood donation that are far from accurate. A blog post published on John Kang WebMD dispels these misconceptions and seeks to enlighten the public, particularly those outside the medical profession.

A new blog post on leading online medical information reference John Kang WebMD exposes several misconceptions about blood donation. As blood donations play a crucial role in the saving of lives, the post corrects these inaccurate beliefs.

Emergencies arising out of disasters and accidents often require sufficient supplies of donated blood to replenish the lost blood of victims. While blood banks and donation facilities have been cropping up all over the country, many people hang onto the myth that blood from fresh donations is still the best. John Kang WebMD, however, says that with new technologies, blood stored in banks can be optimized for up to 42 days. Blood supplies may degrade over time, but it can still be safely used for blood transfusion.

John Kang WebMD also disputes the belief that you can get sick from transfusion of donated blood. Most blood banks and donation centers are licensed by health authorities and they undergo stringent processes to ensure safety.

Those with medical histories, adds John Kang WebMD, can still donate blood as long as their conditions allow it. There is also no particular age bracket for blood donors. Teenagers as young as 16 can donate, and those advanced in age can do so provided their health permits it.

The notion that gay men cannot donate blood is also refuted by John Kang WebMD, although there are special conditions to consider. According to the Foods and Drugs Administration, men having sex with men must wait at least 12 months after their last sexual contact before donating.

John Kang WebMD cautions though that, as with any activity, health may deteriorate after blood donation. Rest is recommended after donating. Lost fluids will be replaced within hours, but red blood cells will be replenished after 3 to 4 days, while white blood cells will regenerate in about three weeks, says John Kang WebMD. Healthy donors will have a shorter recovery period. For more information, visit
