Why get tested? PT/INR test (prothrombin time/international normalized ratio measures the time duration of clotting of blood in a blood sample. INR is a calculation performed on the results of the PT test. Disorders of the coagulation system can harm any part such as the legs, arms, brain, and abdomen. The main types of coagulation problems are as follows: Liver disease Vitamin K deficiency Disseminated intravascular coagulation Synthesis of circulating anticoagulants What is being tested? PT/INR test (prothrombin time/international normalized ratio measures the time duration of clotting of blood in a blood sample. INR is a calculation performed on the results of the PT test. The liver synthesizes the prothrombin protein. This hormone is one of the many substances which are collectively called clotting factors. Blood clotting is necessary for the healing of wounds. Preparation needed? No Fasting required? No
Why get tested? The RA factor test is used for diagnosing autoimmune disorders such as arthritis. Rheumatoid arthritis is an inflammatory and autoimmune disorder, that causes the immune system to mistakenly attack the healthy cells in the body. This results in inflammation or painful swelling in the affected regions of the body. Mainly RA attacks the joints. Commonly, RA attacks many joints at the same time. Moreover, it may also affect the knees, wrists, eyes, heart, lungs, and hands. It causes inflammation in the joint’s lining, which damages the joint’s tissue. The damaged tissue causes chronic or long-lasting pain, deformity, and lack of balance or unsteadiness. What is being tested? An RA factor test determines the number of rheumatoid factors in the blood. Rheumatoid arthritis (RA) factors are proteins synthesized by the immune system. Generally, the immune system stops disease-causing agents such as bacteria and viruses, however, a disorder of the immune system can also make it attack healthy tissues and organs in the body. The most common reasons for high quantities of RA factor in blood specimens are autoimmune disorders, especially rheumatoid arthritis. Preparation needed? No Fasting required? No
Why get tested? SHBG test is to understand the low testosterone condition. This is because SHBG is the primary hormone that regulates the testosterone quantity in the tissues of the body. The sex hormone-binding globulin (SHBG) transports the testosterone hormone throughout the blood by attaching it. The SHBG transports two main hormones; the SHBG test primarily analyzes testosterone transport. Low testosterone may indicate an androgen deficiency among men. This test also analyzes the symptoms and signs of excess androgens in women. What is being tested? The liver produces the SHBG protein. The quantity of SHBG in the blood indicates any deficiency or excess of the testosterone hormone. Preparation needed? No, but before taking this test, inform the doctor about any medicines or supplements that you take. Fasting required? No
Why get tested?The T4 hormone is necessary for several crucial functions in the body such as growth and metabolism. The T4 test is one of the crucial tests for analyzing the function of the thyroid gland in the body. High T4 levels are a sign of hyperthyroidism which is overactivity of the thyroid gland. Many health problems can trigger hyperthyroidism, such as toxic multinodular goiter or thyroiditis. Moreover, high protein levels in the blood can also cause high T4 levels. Conversely, low T4 levels indicate hypothyroidism, which is under-activity of the thyroid gland. What is being tested?The T4 test measures the quantity of the T4 hormone in the blood. This hormone is also called thyroxine hormone and it is synthesized by the thyroid gland in the body.Preparation needed?No, there is not any specific preparation necessary for the thyroxine blood test. Fasting required?No, but if you have been prescribed more tests along with this test, you might require to not drink or eat for some hours before the test. In that case, the healthcare provider will guide you about the preparatory procedures, if any.
