Hi, I am getting myself in a tangle. Hubby went for his routine blood tests today. I think it's every 6 months. He has high blood pressure so is on amlodipine 5mg, Losartin100mg and omeprazole 20mg. He went for bloods this morning and was sent a text saying one of his tests needs repeating. The drs was closed when he got the text. I'm panicking! He's been taking protein powder etc. Could that have effected it?
