Things you should know about Blood Testing

What is a blood test or a full blood count test?
A blood test is when a sample of blood is drawn for analysis in a laboratory. Doctors order blood tests to evaluate things like the level of glucose, haemoglobin, or white blood cells. This can help detect problems, such as an illness or medical condition. Sometimes blood tests can help them see how well an organ (such as the liver or kidneys) is working.

What is a complete blood count?
A complete blood count is a blood test that helps the doctor know the total number of several different types of blood cells. A complete blood count measures:

•  red blood cells, which distribute oxygen to different parts of the body
•  white blood cells, which help fight infection
• platelets, which help the blood to clot, stopping bleeding.

Why is this test done?
A complete blood count may be done as part of a regular medical checkup, as a screening test, or because you’re not feeling well. The total number of red, white blood cells and platelets in a person can provide information to doctors about possible health problems, such as anaemia, infections, inflammation, and other conditions.

How should we prepare for the complete blood count test?
You can eat and drink normally unless another test is required at the same time that he requires a prior fast. Tell your doctor about any medications you are taking because there are some medications that can influence the test results. Also, tell the doctor if your have had a blood transfusion. Both of these things can affect the complete blood count and can help with the result of the MCHC blood test.

How is the test done?
In most blood tests, a sample of blood is drawn from a vein. To this end, a health professional:

• clean the skin
• places a rubber band (tourniquet) around the area to make the veins swell with blood.
•  inserts a needle into a vein (usually in the arm, either the inside of the elbow or the back of the hand)
• Insert the blood sample into a vial or syringe.
•  remove the gum and remove the needle from the vein
• In infants, blood can be drawn from a heel stick.
• Taking a blood sample only causes temporary discomfort and all you feel is a brief pin prick.

How long is the test?
Most tests only last a few minutes. Sometimes it can be very difficult to find a vein, so your healthcare professional may have to try it more than once.

What happens after the test?
Your healthcare provider will remove the rubber band and needle, and then cover the area with a cotton ball or bandage to stop the bleeding. After removal, a small bruise may appear, which should disappear in a few days.

When are the results ready?
Blood samples are processed using a machine, and the results can take anywhere from a few hours to a day to be ready. If the test results indicate a possible problem, the doctor will order other tests to find out what the problem is and how to treat it.

Is the complete blood count test associated with any risk?
Complete blood count testing is considered a safe procedure and is associated with minimal risks. Some people get dizzy when blood is drawn.

It is common for a small bruise and/or mild muscle pain to appear in the area of ​​the puncture, which may last a few days. Seek medical help if your discomfort or discomfort gets worse or lasts longer.
