Why get tested? The TSH test helps diagnose hyperthyroidism and hypothyroidism which are among the most common thyroid gland disorders. What is being tested? TSH test measures the TSH hormone levels in a blood sample. This hormone is secreted by a gland present below the brain region called the pituitary gland. The function of the TSH hormone is to regulate the activity of the thyroid gland. The thyroid gland secretes important hormones and pours them into the bloodstream. The two essential hormones produced by the thyroid gland are thyroxine and triiodothyronine. The thyroid gland synthesizes the TSH hormone, hence the TSH test analysis the activity of the thyroid gland. Thyroid hormones regulate metabolism, the storage, and the release of energy within the body. TSH affects weight gain or weight loss as it impacts the burning of calories & metabolism in the body. It also affects brain & bone development as well as the digestive function in the body. TSH levels regulate the body temperature, increasing and decreasing it. TSH affects the cholesterol level, rate of heartbeat, and blood pressure. An excess of thyroid hormone in the body increases heart rate. Thus, an increase in heartbeat is one of the symptoms of hyperthyroidism. Preparation needed? No Fasting required? No. But fasting can be required if the healthcare provider has prescribed other blood tests along with the TSH test.
Why get tested? The main health problems that the uric acid test diagnoses are gout and kidney stones. Uric acid tests show abnormal results if the body synthesizes excessive uric acid or does not release it sufficiently into the urine. If uric acid does not pass into the urine, then it forms crystals in the joints. This condition is called gout. Gout causes inflammation and pain in and adjacent to the joints and it is a type of arthritis. Kidney failure and kidney stones cause high uric acid levels in urine. What is being tested? The uric acid test measures the uric acid waste product in the urine or blood samples. The breakdown of purine chemicals in the body forms uric acid. Many foods as well as cells in the body contain purines. Only a small part of uric acid in the body dissolves in the blood and most of it moves to the kidneys which then pour into the urine. Preparation needed? No Fasting required? No
Why get tested? Urinalysis test analyzes a sample of urine to detect any infections, particularly urinary tract infections, metabolic diseases, diabetes, kidney, or liver problems. This test diagnoses intense infections in their preliminary stages. The other name for urinalysis is the urine test.

Why get tested? The Vitamin B-12 test has various purposes such as maintaining the health of the blood cells and nerve tissues. It also helps to synthesize the DNA, which is the genetic material. Moreover, this vitamin also prevents megaloblastic anemia. It has an essential function in the myelination and development of the central nervous system. This vitamin is essential for the catabolic and anabolic processes in the body. Moreover, it has a critical role in cell division and replication events that include tissue expansions and hematopoiesis. What is being tested? Vitamin B-12 test helps diagnose megaloblastic anemia which leads to extra-large red blood cells in the system and low hemoglobin levels in the body. Preparation needed? Vitamin B-12 test could interfere with the biotin supplement which is also called coenzyme R, vitamin H, or vitamin B7. Individuals who take high doses of the biotin supplement need to stop taking it for at least 72 hours before the sample collection for the vitamin B12 test. Fasting required?
