Your blood is responsible to carry nutrients, minerals, body fluids and most importantly, oxygen to different parts of your body. Whenever your body is attacked or affected with infection, inflammation or any other disease state, it produces chemicals that notify your system that something is wrong. This is why, for most types of disorders, a blood test is carried out to diagnose a health condition.
Blood tests can say a lot about your system functionality. Therefore, they are divided into varied types that serve a specific medical purpose. As a patient who is undergoing such a test, there are some things that must be known before you take a blood test.

Blood test can be in a form of a singular test or group tests (also known as a profile). A profile contains more than one type of blood test or more than one type of diagnosis in a single test. For example, in a thyroid profile, blood is sampled to learn about levels of T3, T4, T3RU and TSH.
Other types of blood tests include blood culture test, smear test and other types. Blood culture test is performed to study specific types of infections. Blood in such test is cultured and kept under observation to learn about the nature of infectious microorganisms in your blood. A smear blood test is a microscopic examination of your blood for variety of medical reasons.

Blood analysis for counting the amount of a particular substance should be within its normal range. If the count exceeds or becomes less than its normal range, body tasks begin to alter. This causes minor to major problems with respect to the substance we are addressing.
Note that the normal range of measurements for blood tests differs in men and women.
Few types of tests need a proper follow-up of diet, 1-2 days prior to the day of test. Some are asked to avoid specific food items or beverages (alcoholic/non-alcoholic) 2-3 days prior to the test, whereas others are asked to fast, hours before the test. The change in diet depends on the type of test you are taking.

Test reports will be considered according to a pregnant state of that patient.

Even though the disorder is treated, patients experience risks and complications after the cure. You should inform the lab assistant about your previously diagnosed disorder which may be one of the problems that reflects on your test results. risks and complications, even after a cure.
7. Health history (hereditary)
The study on your blood samples will be done with respect to certain points. One of them is your family’s health history. A hereditary health issue can be seen in your blood reports. This is why you should keep your physician informed in advance about the same.

9. Number of samples required for your blood test
For some tests, it is important that blood samples are collected by lab assistants on more than one occasions. This step depends on the type of examination you will undergo. So be well prepared. Carry a packet of biscuits containing glucose or juice to keep you energetic after you have provided your blood.

Some patients show sudden reaction on their skin or body area from where blood is collected. On the other hand, few cases may require an immediate precautionary measure, right after the test is conducted. For example, the point of injection can lead to swelling or any other issue after the test is done. Using an ice pack can help reduce it.
Remember all the above points. They can be useful for you in some way. Apart from the mentioned ones, there are general points that every patient must consider. If you have symptoms like weakness, fatigue, or any thing associated with a low energy, carry an energy drink or ORS supplement. Take at-least one glass of it after you have given blood.
