What Should You Do After Receiving Abnormal Blood Test Results?

A file arrives, you open it on a phone in a hotel room, and one line is marked. Almost everyone then does the same two things: reads the rest of the page much more carefully than before, and types the marked word into a search box. This guide is written for that exact half-hour. It cannot tell you what your result means, and it will explain why that is not evasiveness but the only honest position — then set out what is genuinely useful to do while you wait to speak to someone qualified.

A flag is not a diagnosis, and this page will not pretend otherwise

The marks printed on a report are produced by comparing your figure with the range that laboratory uses for its method and its population. They are a sorting device to draw a clinician's eye, not a verdict on your health. A marked line can be unremarkable for you, and an unmarked page can still leave a clinician with questions, which is precisely why the comparison belongs to a professional who knows your history, your medication, the reason the test was done and what else is going on.

What to do in the hours before you can speak to someone

Start by working out who the result belongs to. If a clinician requested the test, the report goes back to them, and the question you ask is short: you have the result, here it is, when can it be discussed. If nobody requested it — you booked it yourself — then it currently has no reader, and arranging one is the whole task. Our guide on having results reviewed remotely covers that route, and the companion piece on results with no requesting clinician covers what usually follows the review.

While you wait, send the report complete rather than a photograph of the single marked line. Cropping is the most common mistake and it removes exactly the context a reader needs: the other items, the units, the laboratory's own comparison column, the date and the method. Write down anything you think is relevant — recent illness, new medication, the reason you had the test, how you have felt over the last days — and keep it with the file. That note takes five minutes and makes the eventual conversation much shorter.

Things not to do with a marked result

Do not change, stop or start any medication on the strength of a report. That includes something a pharmacist suggests in passing, something a relative takes for a similar-sounding reason, and anything you already have in a bag. Dose and treatment decisions belong to the prescriber, and a single unexplained figure is the weakest possible basis for altering a routine that someone set deliberately.

Do not arrange a repeat test on impulse either. Repeating without a question attached usually produces a second page with the same problem, and sometimes a slightly different figure that creates more confusion rather than less. Whether to repeat, when, and at which laboratory is part of the interpretation, not a shortcut around it. And do not post the report in a travel group for opinions: you will receive confident answers from people with no access to your history, and you will have published your own medical information to strangers.

When waiting is the wrong choice

None of the above is an argument for patience at all costs. A report is a snapshot of a moment that has already passed; how you feel now is current information, and it outranks a pending discussion. If you are becoming more unwell — anything changing sharply, anything you would not have tolerated at home — seek assessment rather than waiting for a review appointment, and mention that a result is outstanding when you do.

If the situation could be life-threatening, stop reading and act. Serious breathing difficulty, severe chest pain, loss of consciousness, stroke-like symptoms, a severe allergic reaction, uncontrolled bleeding or major trauma need emergency care immediately; in Türkiye that means calling 112 rather than waiting for a clinic reply, an online consultation or a private visit. Being uncertain about the severity is itself a reason to say so out loud when you ask for help, and a responsible service should redirect you rather than defend its own booking path.

Carrying the question home

Many travellers will not resolve this before their flight, and that is often reasonable if a clinician has said so. What matters is that the question leaves the country with you in a usable form. Keep the complete report as the laboratory issued it, with every page and the laboratory's identifying details intact, along with the note of context you wrote and any instruction you were given here.

Then close the loop at home deliberately rather than assuming your own doctor will hear about it. Tell them when and where the test was done, why, and what you were told. A report from an unfamiliar laboratory in another language takes a moment longer to read, so give them the document rather than a summary from memory, and say plainly which part was marked. That is the whole handover, and it is the difference between an open question and a forgotten one.
