Diagnostics and laboratory
Tests are requested when the answer would change what happens next. Before a test you should know what is being looked for, how long results usually take and how you will be told. Results are explained in the context of your history rather than read out as numbers alone.

What this covers
- Requests for blood and other laboratory tests
- Sample collection appointments
- Referral for imaging where clinically indicated
- Explanation of results and what happens next
- Repeat testing intervals where monitoring is needed
Preparing for the appointment
- 01
Check whether fasting is required
Some tests need no food or drink other than water beforehand. This is confirmed when the test is requested.
- 02
Ask how you will get the result
Knowing the expected route and rough timing in advance avoids uncertainty afterwards.
- 03
Keep hydrated before a blood test
Ordinary water intake beforehand makes sample collection easier and quicker.
General information, not advice
This page describes how appointments in this area of care usually work. It is general information and cannot take account of your own history, so it is not a substitute for an individual consultation. If symptoms are severe or worsening quickly, seek urgent care; in an emergency, call your local emergency number.
