Everything you should know before taking a blood test

Regular blood testing in a blood test lab is an excellent way to track your overall health and other health-related issues. For people who are struggling with chronic illnesses, it is one of the most important ways to keep track of your overall physical well-being.

How many times can you take a blood test?

Generally, your doctor will recommend that you should get a routine blood test done at least once a year to ensure all the body parameters are fine. This can be done around the same time as your yearly physical checkup. 

However, there are several other and major reasons because of which you may want to get blood tests done more often than once a year.

These reasons can be as follows:

  • You have persistent discomforting symptoms like fatigue, weakness, or pain.
  • You have a persistent fever.
  • You have chronic gastrointestinal issues.
  • You’re noticing abnormal weight loss.
  • You’re noticing abnormal weight gain.
  • You’re noticing unusual symptoms like skin rashes.

If you are in Bahrain and want to optimize your health, then knowing the levels of various blood components can allow you to tweak your diet or fitness plan to minimize the damage you are unknowingly doing to your body. It’s important that you visit a good diagnostic centre for your blood test.

What are some routine tests?

Some of the most common tests taken on a routine basis in blood test labs are as follows:

  • Complete blood count (CBC)
  • Basic metabolic panel
  • Thyroid panel
  • Liver function test
  • Kidney function test
  • Nutrient tests for levels of vital nutrients, such as Iron, Vitamin C, D, K, Folic acid, and B12.
  • Enzyme markers ( if you’re at risk for cancer or other conditions like liver cirrhosis, stroke, or celiac disease )
  • Sexually transmitted disease (STD) tests ( if you have multiple sexual partners )

What should you do before a blood test?

Often, blood tests are hassle-free and don’t require a lot of preparation. You can visit your doctor’s clinic, get a checkup done, and take your doctor’s prescription straight into the diagnostic centre to get the prescribed tests done.

However, at times your health care provider may ask you to fast before taking a blood test as eating right before a blood test can spike your sugar levels, and consuming vitamin and protein supplements can alter your results too. 

Therefore, many parameters in your blood can temporarily spike or drop if you’re not careful. Fasting for 8–12 hours before some specific tests help ensure that the results are free from any misleading variables. 

Some common tests that may require fasting include:

  • Blood sugar tests
  • Glucose tolerance test
  • Cholesterol test.
  • Liver function tests
  • Kidney function tests
  • Thyroid panel.
  • Basic metabolic panel

Make sure to drink a glass of water before your appointment at the diagnostic centre as when you’ve hydrated your veins are plumper and easier to access.

What should be done after taking a blood test?

Blood tests take a minute to complete at the blood test lab and diagnostic center & don’t cause issues when done right.

Here are some things to take care of after a blood test is done:

  • Maintain pressure over the area of needle prick.
  • Keep the bandage on for the recommended amount of time, usually 4 to  6 hours after your blood draw.
  • Apply a cloth-covered ice pack to your arm or hand if you have soreness or bruising at the puncture site.
  • If you experience rashes on the site of needle prick inform your doctor immediately.
  • Refrain from doing any vigorous exercise as it may cause bleeding at the site of the prick.
  • Eat a healthy diet after the test is done.

If you’re someone who gets blood tests done quite often, then you can have foods rich in iron, such as leafy green vegetables or iron-fortified cereals. These can help replenish lost iron stores to build your blood supply back up.

You’re in Bahrain booking for a blood test to be done. It’s important that you visit an authorized and safe diagnostic centre to get all your blood work done.

When should you expect to get a report?

After taking a blood test you may have to wait from a few hours to a few days for the test results to be made available by the diagnostic centre. The time duration depends on the blood test lab you’re getting tested at, the type of test you’re taking and the methods used to test your blood. It also depends on how many tests you get done at once; If you order multiple tests, you may not get the complete results until all of the tests are completed.

Sometimes a blood test lab will only release results to your doctor, who reviews them and then releases them to you.

Here’s a rough overview of how long some common tests may take:

  • Complete blood count – a few hours to 24 hours
  • The Basic metabolic panel between 24-72 hours
  • The Complete metabolic panel between 24–72 hours
  • Lipid panel between 24-72 hours.
  • Thyroid panel between 24- 72 hours.


Regular blood tests can catch the warning signs of almost any disease early. Many heart, lung, and kidney conditions can be diagnosed using blood tests. So get your blood work done routinely from a safe and authorized diagnostic clinic under your doctor’s supervision to reduce the risk of diseases.
