Do you know that every 2 seconds, someone in the world needs blood?
On the second War, in Vietnam over 58,000 soldiers were killed and 25% of them was died because of hemorrhage.
It’s fantastic when something from your body can really save a life without paying anything. Unlike the daily products, blood is a unique product as part of a billion-dollar business.
Blood donation not only good for donors health because they are actually at a lower risk for heart attack however it does not demand from everyone.
Due to the harsh conditional to maintain the quality of blood and it’s also a very meaningful product, I was curious about the supply chain of blood and the content below is what I found out about its journey.
Figure 1. The supply chain of Blood
- Donor registers with a form of health check-list
- About 1 pint of blood and several small test tubes are collected from each donor
- Every blood units are poised in the bag test tubes and the donor record are labeled with an identical bar code label to keep track of the donation
- The donation is stored in iced coolers until it is transported to a Blood Center
- From Blood center, the blood packs are sorted and registered in the manufacturing area. Donated blood is scanned into a computer database
- In here, each donation is tested to find out the donor group and checked for viruses to help ensure that each donation is safe to transfuse to patients.
- This is one of the most important steps during the whole supply chain process
- When test results are received, units suitable for transfusion are labeled and placed into controlled storage
- Red Cells (which plays an important role in your health by carrying fresh oxygen throughout the body) are stored in refrigerators at 6ºC for up to 42 days
- Platelets(tiny blood cells that help your body form clots to stop bleeding) are stored at room temperature in agitators for up to 5 days
- Plasma and cryo are frozen and stored in freezers for up to one year
- Blood is available to be shipped to hospitals 24 hours a day, 7 days a week.
- Most deliveries to hospitals go unnoticed by the public but sometimes an urgent delivery may require a vehicle with sirens and blue flashing lights to get to the patient as quickly as possible. After some checks, the blood is ready to be transfused.

Interesting knowledge of writing this blog:
- Blood can be stored up to one year after the donation
- Gay men or a man “slept” with another man can’t donate blood
- One donor can save up to 3 lives
- Vitamin K is to contribute to normal blood clotting. It plays a vital role to increase the speed of blood clotting at the site of injury and prevent major blood loss. Therefore, a nutrition for blood is vitamin K (especially K1 can be found in foods such as broccoli, carrots, kale, watercress, kelp, eggs and cheese)
