About the Test

The test is also known as T4 or free thyroxine. Thyroxine-Free and a combination of triiodothyronine (T3) together produce thyroid gland. It is through T4 that the body control rate is measured. It is all regulated in a feedback system. The doctor may order the T4 test if the doctor sees the abnormal result on a TSH test or suspects of hyperthyroidism or hypothyroidism. If the patient shows increased high rates, anxiety, sudden weight loss or being the insomnia, tremors in the hands or have visual disturbances, he can be a suspect for hyperthyroidism, and the T4 test can be called in for. Whereas weight gains, dry skin, cold intolerance, fatigue, hair loss, irregularity in menstruation cycle of women, constipation can be symptoms of hypothyroidism.

FAQs

Blood tests are used to measure or examine cells, chemicals, proteins, or other substances in the blood. Blood testing, also known as blood work, is one of the most common types of lab tests. Blood work is often included as part of a regular checkup.
Blood tests are used to:
Help diagnose certain diseases and conditions
Monitor a chronic disease or condition, such as diabetes or high cholesterol
Find out if treatment for a disease is working
Check how well your organs are working. Your organs include your liver, kidneys, heart, and thyroid.

A health care provider will need to take a sample of your blood. This is also called a blood draw. When a blood draw is taken from a vein, it's known as venipuncture; It is the most common type of blood collection.
Most blood tests do not require any special preparations. For some tests like lipid or glucose tests you may need to fast (not eat or drink anything except water) for around 8 to 12 hours. Your doctor will provide all the instructions, in case any special instructions are to be followed before the test.
"There is very minimal risk with having a finger prick test or venipuncture. During venipuncture, you may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
Collecting blood from an artery is more painful than collecting from a vein, but complications are rare. You may have some bleeding, bruising, or soreness at the spot where the needle was put in. Also, you should avoid lifting heavy objects for 24 hours after the test."
"Blood testing provides important information about your health; however, it does not always give sufficient information about your condition. If you had a blood work, you may need other types of tests before your doctor can make a definitive diagnosis."
