I had never needed blood tests before. My mum donates blood, and I used to like going with her because they gave me sweets while I waited. She also received pin badges afterward to congratulate her on how much blood she’d donated. I never saw any needles, just lots of people lying down on beds in a big hall. I thought, “If blood tests are the same as this, they can’t be that bad, right?”
But with a blood test, they don’t give you treats, and they certainly don’t give you pin badges. (Imagine if they did — we’d have hundreds by now!) Most often, you’re stuck in a tiny room with a nurse, hoping she knows what she’s doing and has done this before.
I don’t know my blood type or what they test in your blood when you have MS, but I do know that we need blood tests. And every medication is different.
I’m on Tecfidera (dimethyl fumerate), and as far as I know, they mainly test my white blood cells (the immune cells) and some other stuff. Sometimes they test my vitamin D, and I have to specifically ask for that.
With Tecfidera, I need to have a blood test every three months or I can’t receive my medication. All medications are different, and it’s best to ask your medical team what you need to do if you’re unsure.
After having so many blood tests over the last five years, I thought I’d pass on my knowledge and my three best tips for having a blood test. These are things no one ever told me.
1. Drink a pint of water an hour before.
I used to pass out every time I had a blood test. So much anxiety and fear would build up that I couldn’t eat or drink anything. As it turns out, this is not helpful, and you need to drink at least a pint of water an hour before. Bonus tip: Have something sugary or sweet on hand for afterward. (I imagine that’s why we get sweets after giving blood?)
Drinking a pint of water beforehand means you are boosting the oxygen in your system, thereby creating more red blood cells. If you don’t do this, you’ll have too little blood in you at the time they take it, and that’s why you pass out — a lack of oxygen.
2. Stay calm.
Stress and anxiety from having a blood test are perfectly normal. I remember sitting in the waiting room, waiting for my turn, and finding myself shaking with fear. I developed some strategies since then and am not nervous in the slightest now.
It is super important to stay as calm as possible and not let fear build up in your mind. When you let panic take over, the brain uses more oxygen from the blood, meaning fewer red blood cells are created, so your oxygen drops. That’s why you pass out. Remember it is only a few seconds, and it’s over in no time. Take deep breaths and practice my anxiety techniques.
3. Ask for help.
A tip I picked up (admittedly, too late) is easy to do. Nurses in the U.K. tend to say “sharp scratch” when they’re about to pierce the skin with the needle, which I don’t find helpful in the slightest. I frequently ask them not to say it. When they do say it, I feel my body tense up for what’s coming. Tensing up often makes it hurt more and gives me a bruise.
Do nurses say that where you are? If not, what do they say?
Another bonus tip: Take a deep breath when you know they are about to pierce the skin. That helps distract the mind, and it makes it hurt less. Two seconds and it’s over.
