In a routine blood test, it might just be to check that nothing has changed since your last healthy test result.
You likely have lots of questions about the process and results.
A routine blood test consists of getting blood taken at your doctor's office or at a lab. That's why doctors encourage their patients to get routine blood work done.
By analyzing the blood, scientists can detect illnesses before it's too late. Or, they can explain why you've been "feeling off" for the last few months.
Getting blood taken can be scary for those who've never done it, especially children. Usually, the technician, nurse, or doctor will have you sit down on a chair with your feet on the ground.
This might seem scary, but it's quite straightforward. It can tell you hundreds of things about your lifestyle and habits. Blood can tell you about your organ function, diet, metabolism, illnesses, and if you have certain diseases. Often you're done in less than five minutes.
What Can Blood Tests Detect? The reasons for getting your blood tested vary.

As a fluid connective tissue, messenger and transporter the blood also performs the transport of hormones and the signaling of tissue damage.Other than imparting immunity to the organism, the blood is also very important in the self repairing mechanism of the body called as Coagulation. Other than the basic transportation function of the supply of oxygen, nutrients and removal of wastes there are also some very vital biological functions performed by the blood. This liquid connective tissue is called as Blood. It plays a major role in the defense mechanism of the body. It basically is a specialized bodily fluid that delivers necessary substances to the cells of the body. Clotting helps repair and heal the injuries on the surface of the body (and also inside the body). Blood performs many immunological functions like circulation of white blood cells, and detection of foreign material by antibodies. The clot hence formed as a result of this process seals an open wound in order to stop bleeding and prevents blood loss. The transport of vital nutrients, oxygen, and drugs and even the waste material, gases etc occur in the body through a liquid connective tissue. Here the transport of the nutrients, oxygen and other beneficial substances occurs from the source organs to the cells via blood and likewise the transport of waste materials, metabolites, harmful gases (including CO2) occur from the cells to the blood.
