Individual tests

IGF-1 is a hormone that manages the human growth hormone's (GH) effects. Together, IGF-1 and GH promote the normal growth of bones and tissues. GH levels in the blood fluctuate depending on your diet and activity levels, but IGF-1 levels remain stable. So, an IGF-1 test is useful for determining if your body is making a normal amount of GH. The test helps diagnose growth disorders.
PTH is a hormone your parathyroid glands make, which helps control the calcium level in your blood. If calcium blood levels are too low, your parathyroid glands will release PTH to raise calcium levels. If calcium levels are too high, these glands will stop making PTH. This test helps diagnose hyperparathyroidism (too much PTH) and hypoparathyroidism (too little PTH), monitor kidney disease, and determine whether high calcium blood levels relate to parathyroid glands.
Iron homeostasis diseases are common and may be attributed to either iron deficiency or overload. Iron deficiency can result from increased loss or inadequate absorption of iron. Iron overload occurs when there is an excess in the binding capacity of transferrin. Iron overload may also occur during the catabolism of red cells. Iron levels are used to help diagnose specific types of anemia.
Luteinizing hormone (LH) is synthesized and secreted by gonadotropes in the anterior lobe of the pituitary gland. Along with the follicle-stimulating hormone (FSH), it is essential for proper reproductive function. In females, an acute rise of LH triggers ovulation; in males, it stimulates Leydig cell production of testosterone. This test typically finds the cause of infertility or irregular or stopped menstrual periods.
Magnesium is a charged electrolyte mineral. It is responsible for many important bodily functions and processes, including ensuring your muscles, nerves, and heart work properly and controlling blood pressure and blood sugar.
Phosphorus is the second most abundant mineral in the body. It is primarily found in bones and teeth, playing a crucial role in their formation. A phosphorus deficiency may cause bone diseases, while an improper balance of phosphorus and calcium can lead to osteoporosis.
Potassium is an electrolyte that regulates your heartbeat and helps your muscles contract and nerves function. Too much potassium in your blood can damage your heart and lead to a heart attack. However, if the potassium in your blood is low, it can cause life-threatening complications, such as an irregular heartbeat or acute respiratory failure from muscle paralysis.
Progesterone is a hormone from the ovaries. During a normal menstrual cycle, progesterone prepares your uterus for pregnancy. This test is useful for those having trouble getting pregnant, undergoing fertility treatment, or experiencing abnormal bleeding when not pregnant.
Prolactin is a pituitary gland hormone that causes the breasts to grow and produce milk. If prolactin levels are higher than normal, it often means there is a type of tumor of the pituitary gland. This test is often used to diagnose a prolactinoma, find the cause of a woman's menstrual irregularities and/or infertility, or determine the reason for a man's low sex drive and/or erectile dysfunction.
SHBG is a protein that attaches to sex hormones in your blood. When the SHBG protein binds to sex hormones, your tissues can't use those hormones. Your tissues can only use free sex hormones that aren't attached to SHBG. The test is most often used to gather information about how testosterone is working in the body.
Sodium is an electrolyte that your body needs to function. It helps to regulate the nerves and muscles and maintains the right balance of fluids in your body. High sodium levels can lead to high blood pressure and other health problems, while low sodium levels may cause seizures, coma, and even death.
Testosterone is known as a "male" sex hormone, but females have testosterone in smaller amounts. Testosterone causes body hair, muscle growth, and a deepened voice after puberty in males. It controls sex drive, maintains muscle mass, and helps make sperm. In females, testosterone is important for the growth of bones and muscles. A testosterone levels test may help diagnose early or delayed puberty.
Vitamin B12 is essential in nervous system function and DNA and red blood cell production. Vitamin B12 tests help detect anemia with larger-than-normal red blood cells or problems with the nervous system, such as emotional changes or weakness.
