Having test results that fall outside the normal range is very common, especially in some of our larger profiles where lots of biomarkers are being tested. Laboratory reference ranges are set by taking the results of a normal population and setting the range so that 95% of that population falls within it. This means that 2.5% of that normal population was above the range set, and 2.5% of people were below it - but they were still normal.
It is our doctors' job to look at your results and put any abnormal results into context. They will look at your medical history and lifestyle information and any further information you have given them (this is why it is so important to complete this information before you take your test). They won't just look at one biomarker in isolation, they will look at other markers to see whether an abnormal result might be significant or not, and they will look at any previous results you may have had with us - a result outside of the normal range may be completely normal for you.
If they think that a result outside of the range is NOT significant they will tell you that in their report. They may let you know any factors that may have influenced that result (e.g. whether you have recently eaten, are dehydrated or recovering from an infection). They may advise you to make some lifestyle changes and then repeat the test in a few months, or they may suggest you repeat the test in a week or two as many abnormal results go back into the normal range without you doing anything at all. If they think a result requires further investigation, they will suggest you go and discuss it with your GP.
The important thing is that if the doctor commenting on your result has said that is not concerning, then please be reassured that it is nothing to worry about.
