How To Get A Blood Test to Determine Overall Health

Blood tests can be used as part of an assessment to determine a person’s overall health. Doctors order blood work for different reasons because it measures several factors and gives an insight into how well the body is functioning.

Although blood tests are essential in delivering quality health care, most people do not like the procedure involved in getting a full blood test in London. The idea of someone inserting a needle into their body, and extracting blood for the blood test causes most people to feel nervous. The good thing about getting a blood test is that the procedure is a short one and afterward, you are sure that your doctor will have all the information needed about your health.

Your doctor is in the best place to let you know if you need a blood test. Your doctor will access your signs and symptoms, and if you require further assessment, your doctor will ask you to get a blood test done. 

If your doctor orders blood work, ensure you do it as soon as you can. Make sure you follow the instructions your doctor gives you concerning the things you need to do before and after your test.

  • Discuss with your nutritionist

Getting a blood test without a blood work order

Nowadays, many laboratories let individuals get a blood test without order or prescription from a medical professional. Although this is now common practice, it is not advisable because,

  • When you get a result, a doctor would not interpret it and prescribe a medication for you.
  • The information you may get on the internet concerning the interpretation of your result may be misleading.

Having your blood drawn

  • Prepare for your blood test.

You may need to make special preparations before your blood test depending on the kind of blood work your doctor ordered.  These preparations would ensure that your result is accurate. Common preparations before a blood test include not eating or drinking for up to 12 hours and discontinuing the use of some medications.

  • Take your prescriptions to a hospital or lab.

When you get your blood work order form your doctor, take it to a hospital or lab that specializes in collecting blood work and other specimens for analysis. The lab will likely run the test or send it off to a central location for testing. 

  • Provide the phlebotomist with necessary information 

A phlebotomist specializes in extracting blood samples from patients. Ensure that you cooperate with the phlebotomist and answer all the questions you will be asked. This will help the specialist verify your identity, calm you, and know if you have any allergies.

  • Relax and let the phlebotomist draw your blood

Ensure that you relax your arm and position your hand in a way that your palm would be facing up. This would help make finding your vein and drawing the blood easier. Drawing your blood sample would only take a short while.

The phlebotomist would locate your vein and disinfect the area with an alcohol swab. Next, the phlebotomist will tie a tourniquet around your arm then position the needle at a 15-degree angle before inserting it into your vein. This would only sting a little. The phlebotomist will then draw your blood for about 30 seconds to a couple of minutes, depending on how much blood is needed and, how many sample tubes need to be filled.

Why should you get a blood test?

You should get a blood test for the following reasons. 

  • Routine monitoring

The test is essential because it measures blood sugar levels, cholesterol levels, red and white blood cell levels which are essential in health assessment.

  • Unidentifiable illness or pain

Your doctor would order blood work if you are ill and, the cause of the illness is not known. The result of the blood test would help the doctor identify the cause of the ailment to prescribe the right medication.

  • Exposure to dangerous contagions
