Everything You Should Know Before Drawing Your Blood


Your provider has asked to conduct blood work and you are all set to get it done. Read on to know what you must be aware for a comfortable and easy blood drawn.

Before the blood test

Your provider should know if you need to fast before drawing blood. If you aren’t sure about it, make sure you confirm the exact requirement from the provider.

Fast in a smart way

When you do fasting for a blood test, it involves not taking all food and beverages except water for the next 8 to 12 hours, before the test. Make sure you drink sufficient amount of water and take necessary medications. Even a few tests will have strict requirements like H.pylori breath test that means drinking water only for one hour before the test.

Tip: You should come prepared with some snacks on the test day. Go to the laboratory directly in the morning and carry a healthy snack following the blood test.

Drink sufficient amount of water

Many people think they should not drink water before drawing the blood but this is not correct. When you drink water, it will make you feel much better during fasting and ensure a smooth blood draw. Your blood consists of almost 50 percent water and so, the more water you may drink, the plumber the veins will be. Also, it might be quite easy for the phlebotomist to draw blood and then locate the veins for removing the blood.

Urine tests are generally ordered together with blood tests and the fuller your bladder might be, the easier it will be for you to provide blood sample. The urine test done for gonorrhea and chlamydia requires you do not urinate for one hour before the test.

Tip: Make sure you stay hydrated by drinking extra water at the starting of the day before draying blood. This will ensure you are properly hydrated the day of the blood draw.

Insurance coverage

Do you need to perform an unusual test and you are wondering whether your insurance policy will provide coverage for it? It is suggested that you call your insurance provider and know the details about it. If your insurance won’t cover the cost of a test or you do not have insurance, then you will have to look for different option for conducting private blood tests.

Look for a laboratory order

You will require a laboratory order from the provider to draw your blood. If you do not know whether you have an order on-file, call the clinic and we will have a look at it. If you want your provider to order for blood work, it is suggested to fix an appointment so that you may discuss about your concerns and know the set of tests to perform.

What you can expect during the blood draw

No one wants to draw their blood but the procedure is ordinary and short. Most people enter inside and come out of the laboratory within 15 minutes at the most. The phlebotomist starts by pressing his/her fingers gently against your skin to locate for the best vein. After this, he/she will wear gloves to clean the area by using an alcohol pad and tying a tourniquet around your upper arm to increase flow of blood. He may ask you to make a fist and then insert the needle accordingly.

Tip: The phlebotomist will keep you engaged in different conversation to make you feel relaxed so that the needle prick is less painful. Chat with your phlebotomist and try to distract yourself completely from the blood draw.

Shy Veins

The phlebotomist draw blood from several patients and some veins seem to be tricky than the others. If you have shy vein, then the phlebotomist might tighten the tourniquet, place a warm pad against the skin and spend extra time for palpating your veins. The aim of a phlebotomist is to draw your blood easily and painlessly only once! If the phlebotomist does not attain success even after two sticks, then he/she might recommend you come another day.

Tip: Make sure you are aware of your limits and if you have fainted earlier or have a phobia of different needles, then you should tell the phlebotomist about it. He will position you in a way so that you have fewer chances to faint, keep the needles out of your eye sight or use the right words to soothe you during the blood draw.

After Your Blood Test Bruising is normal

After the blood draw has been done, your phlebotomist removes the needle, holds gauze against the puncture site, and asks you to apply more pressure. When you put pressure directly after a blood draw, then this mitigates common side effect of bruising.

Even by taking necessary precautions, minor bruising and swelling around the puncture site may take place. Since every one has different veins and they usually move often, bruising can take place with the most experienced phlebotomist. If you do bruise, it should go away within a few days.

Getting your test results

Your blood samples will be sent to an outside laboratory. After the lab processes these samples and sends the results, a provider will send you an email with interpretation of the results and a file of the results for further reference. If it is already more than ten days since your blood draw and you have not received an email, call at the clinic.

Do you need to conduct blood tests every year?

The providers conduct necessary tests for specific concerns only based on your symptoms, personal and family history as well as risk factors. Testing for particular concerns than ordering every test ensures you will not end up receiving probable harmful treatments for the diseases that you do not have. It should also enable you to keep the health care costs lower than expected.

In case you develop newer symptoms, have experienced significant changes in your lifestyle, or want to get a specific test done for any reason, it is advised to schedule an appointment with your provider so that you can discuss about it together and know if a blood test is the right course of action for your case.
