Medical diagnosis tests are done in order to determine the medical condition of a patient. Depending on the patient’s symptoms, specific tests are usually done. Now, if you have noticed, there are some medical diagnosis tests that require you to do some preparations. It is really important that you follow the instructions completely.
Here are some diagnosis tests that need preparations. Blood tests for sugar levels, cholesterol/lipid profile, etc. would usually require you to fast for around 12 hours. That’s strictly without any food and water. For tests that require or involve physical activity such as Cardiac Stress Test and Video Nystagmography (usually for vertigo), you need to have a good sleep the night before the test and then eat a light meal around 1-2 hours before the procedure.
There are also short term preparations for a couple of tests. These are instructions that you can accomplish minutes before the procedure. For Radiology tests such as X-Ray, CT scan, MRI, and even ECG, you need to take off any electrical or metallic objects such watches, belt buckles, coins, etc. so as not to interfere with the machine.
I also had a blood glucose tolerance test where I had to drink some sort of solution that is so sweet (much like orange juice) then they will test my blood. I would have to come back after an hour (without taking in anything, even water) and see if my blood glucose goes down.
The main reason why there are preparations before medical diagnosis tests is for the results to be accurate. Just imagine eating 3 creamy chocolate bars and a pint of ice cream an hour or so before a blood test, your sugar levels will shoot up. Or if you are tired before a procedure, your test results will say you were weak but actually you just lack sleep or just plain tired.
If you have to do something that will get in the way of your preparations for a medical diagnosis test, make sure that you call the hospital or the facility where you will have it done. This way, they can give you further instructions or set the appointment date at a later time.
So if you were given instructions on what to do before a diagnosis test, always follow them. It’s much better to have accurate test results. It will give your doctor a very big chance to diagnose your condition correctly and thus give you the right treatment/s. Hidden ailments would usually appear in the results as well.
Just remember, not all preparations are the same even for similar procedures such as the different blood tests. The medical staff would most likely explain to you what you need to do. If you have questions, do not hesitate to ask. They can give you advice when you need it.
