    Dear Science: If I Drink Coffee Before Giving Blood Will Recipients Get A Buzz

    Dear Science: I gave blood recently after drinking coffee and can’t help but wonder will any of the recipients of my caffeinated blood feel a caffeine jolt??? Thank you, I love reading the science column!

    Here’s what science has to say:

    We hope you’re not exceeding the maximum recommendation of five cups of coffee a day, but something about your choice of punctuation suggests otherwise. Just remember: A serving of coffee contains about 100 mg of caffeine. Consuming more than 500 or 600 mg a day can make you nervous, irritable, twitchy and nauseated, among other things.

    The good news is that the recipient of your generous blood donation probably didn’t notice a blood buzz.

    “I know of no data that shows that it would have an impact on the recipient,” said Jerome Gottschall, senior medical director of the BloodCenter of Wisconsin.

    In fact, to our knowledge, no one has bothered studying this question at all: The researchers we talked to agreed that it was a fun one to talk about, but it just doesn’t rank high on the list of concerns about the safety of the blood supply.

    “Probably lots of donors have caffeine in the morning and donate sometime in the day, and this has gone on forever and ever,” Gottschall said. “And for the most part that has no effect on the donor themselves.”

    Can I Donate Blood On My Period

    You can safely donate blood during your period if it is required and your period will not be affected by the donation. If you dont have a history of blood clot, your haemoglobin is more than 11 g/dl, and you are not bleeding heavily, donating the week after periods is still manageable. If you have had a blood transfusion in the past, you may need to wait a few days before you can donate.

    This is because the red blood cells need time to re-aggravate, which can take up to 24 hours. You can check the status of your blood donation by going to your nearest blood bank and asking to see your donor card. If the card shows that your donation has been accepted, it means that the blood is ready to be transfused.

    All blood groups are suitable for plasma donation, but we are particularly keen to welcome donors with blood group AB. This is because their FFP is universal and can be given to patients of any blood group.

    Plasma donors must meet the same health criteria as blood donors. We do some extra tests for plasma only donors, such as protein levels to make sure it’s safe for you to continue to donate. We will also test Plasma for Medicine donors for Hepatitis A and Parvovirus B 19.

    You can give a Plasma for Medicine donation from four weeks after your last blood donation.

    Can You Drink Caffeine Before Donating Plasma

    If you are drinking alcohol, also consume extra water that can maintain the blood profile. It needs to be in a healthy range before you are allowed to give blood, so you are assured the experience of giving blood is not going to make you sick or make you anaemic. The best way to give blood is to have a balanced meal at least three hours before you donate, avoid hamburgers, fries, or ice cream, and avoid high-fat foods. Caffeine causes your blood vessels to narrow, making it harder to find your veins and get back to your donor with non-plasma portions of blood. It is important that donors are in good health and feeling good prior to, and on, the day of donation. When losing fluids in the process of giving blood, blood pressure may drop, leading to lightheadedness.
