General blood tests can be carried out anytime. For instance, CBC (complete blood count) takes place anytime of the day. However, drinking and eating can affect when you need to check the level of blood glucose. In such cases, you need fasting prior to the test means no drink or food before withdrawing the blood.
Why fasting becomes mandatory for some tests not all?
Scientifically, drinking and eating affects the blood composition. So, most common blood tests deem fasting beforehand. For instance, after eating, body secretes insulin hormone that drops down the blood sugar or glucose level. Also, it is absorbed by the body.

If you then on medication, ask the doctor if they can affect the result of the blood test. Generally, you have to continue the medication despite of having the blood test. The doctor informs if you need to stop any medication for the time being. Consult with the doctor prior to stop taking any medication to know it, they really can interfere with the result of the blood test.
Nervous feeling or anxiety is common before the blood test. Most people feel the tremor of needle insertion. In case you have no phobia to the needle, then also you will feel slightly anxious. But you do overcome the situations to calm down yourself:
- You can attend the testing clinic with someone
- Share your worries with the Phlebotomist, nurse and doctor. They can reassure you about everything
- Drink plenty of water for hydration before the test
- Put on the warm jumper as this will make the veins prominent
- Try to distract yourself by listening to music
If you experience anxiety, then switch on the fight, fright and flight mechanism. This will allow the body to prepare for the action. You will start feeling extremely sweaty and hot with racing pulse.
Blood pressure can drop down drastically. The pupils will dilate and there is dizziness and light-headed. As a result, you can collapse after fainting because of the action starts by SNS (sympathetic nervous system).
Fortunately, you can control it perfectly! Use the breathing technique, namely diaphragmatic breathing for calming down the nerves. It involves filling the lungs with air. When trying to suck the abdomen diaphragm will raise. Attempting this the night before the test can resist you from collapsing completely.
Feeling like faint
Dizziness is also common when you have to go for the blood test. The problem becomes worse once you fear of needles. If you have any such feeling then; share it with the doctor right away. They will make you comfortable by making you sit in a safe to prevent an accident during fainting.
