DH passed out at work the other week and they sent him to a doctors as it was the 3rd time he'd passed out in seven months. He had a heart monitor and all the works etc blood and the doc said he was fine.
Went to see our own doc for something else and they gave DH a blood test. He rang for the results today and they told him to make an appointment to talk to his doctor as he has "high levels of hemoglobin". What does this mean?
