I recently had a full set of bloods done, two different tubes were sent off. One I believe would have gone to the haematology lab which looks at the HbA1c, red blood cells, white blood cells etc... The other would have gone to biochemistry which looks at things like liver and kidney function. I’m just guessing but if they took two tubes from you maybe only one went astray. However I do sympathise hugely, I had had a routine blood test two years ago before I was diabetic just before this Mayday BH w/e, and had a text msg come through after hours on the Friday to say I needed to make an urgent appt! It was it turns out my diabetes diagnosis, I had no clue!
