Yesterday saw us donating blood again. Once more, OH failed the copper sulphur drop test to ensure he had adequate iron levels to donate. A sample was taken from his arm and he was declared fine so this time, he was able to donate. Sometimes the finger blood drop test does fail. One drop of blood has a certain amount of seconds to drop to the bottom of the tube. If it doesn't, they will take a sample from you, test it, then decide.
The men's test is higher than the women's as they have a slightly higher level of stored iron than us. I have only failed once when I tried to donate a couple of weeks after recovering from flu!
Mind you, my donation was a little hit and miss as the machine kept bleeping to indicate my donation was not flowing at the correct rate. Several times they adjusted the needle then after that it was okay.
Most of the time after donating, we feel fine for the rest of the day, occasionally we feel very tired.
That in itself is not surprising when you realise that iron rich red blood cells carry the oxygen around your body. Therefore reduced iron = reduced oxygen = tiredness. Your body wants you to rest until it can get your oxygen levels back up again - usually within 24 hours although red blood cells/iron levels take many weeks to recover to normal.
Yesterday was just such a day. We hardly had the energy to make tea, then I needed to make a raspberry cloud cake for our 'school' B-B-Q tonight. I'm still tired today which is very unusual but I think perhaps the weather isn't helping.
I don't know if you can remember a few posts back me showing you a candelabra of roses forming in the front garden. Well, it is in full, if smaller than normal bloom.
