Why are blood tests taken?
Dr Shaikh may recommend a blood test for a number of reasons. These include checking for an infection, evaluating your general state of health, checking the function of your organs (such as the liver and kidneys), and screening for genetic conditions.
What does a blood test involve?
In most cases, blood tests take only a few minutes to complete. They can be performed in Dr Shaikh's office to ensure your comfort and convenience.
If there is anything you need to know before undergoing your blood test, Dr Shaikh will let you know. In some cases, you will need to avoid eating and drinking for up to 12 hours before a blood test. You may also need to stop taking certain medications before the test is performed.
The blood sample is usually taken from a blood vessel in your arm, as it is usually possible to locate a vein close to the surface of the skin in the inside of the elbow or the wrist.
If your child needs a blood test, Dr Shaikh may choose to take a blood sample from the back of the hand, depending on the age of your child.
Before the sample is taken, your skin will be cleaned with an antiseptic and a tight band will be placed around your upper arm. This helps to squeeze your arm and causes the vein to swell, slowing down the flow of blood and making it easier to take a sample.
The sample is taken with a needle attached to a syringe. While you may feel a slight prick, the test will not be painful.
What happens after the blood test?
It is quite normal to develop a small bruise where the needle was inserted. You should not feel any other side-effects.
Once the sample has been taken, it will be sent to a laboratory for testing. When Dr Shaikh receives the results, he will contact you to discuss the findings.
