This group of tests measures the amount of cholesterol and other fats in your blood. Cholesterol and triglycerides are lipids, or fats. These fats are important for cell health, but they can be harmful when they build up in the blood.

The basic metabolic panel (BMP) is a blood test that gives doctors information about the body’s fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys are working.

A PT/INR test helps find out if your blood is clotting normally. It also checks to see if a medicine that prevents blood clots is working the way it should.

What is a HIV Ag AB test?An antigen/antibody test looks for both HIV antibodies and antigens. Antibodies are produced by your immune system when you’re exposed to viruses like HIV. Antigens are foreign substances that cause your immune system to activate. If you have HIV, an antigen called p24 is produced even before antibodies develop.

This is a panel of blood tests that looks to see whether you have a hepatitis virus infection. The tests may be known by different names, depending on your provider and lab. The tests look for antibodies that your body has made against a hepatitis virus. They also look for parts of a specific virus (antigens).

In women, testosterone tests are used primarily in cases of infertility, absence of menstruation, abnormal uterine bleeding, or if there is a suspicion of polycystic ovary syndrome or other cause of virilization (hoarse voice and hirsutism (abundance of body hair)).

This test measures the levels of testosterone in your blood. Most of the testosterone in the blood is attached to proteins. Testosterone that is not attached to a protein is called free testosterone. There are two main types of testosterone tests: Total testosterone, which measures both attached and free testosterone.

TSH stands for thyroid stimulating hormone. A TSH test is a blood test that measures this hormone. The thyroid is a small, butterfly-shaped gland located near your throat. Your thyroid makes hormones that regulate the way your body uses energy.

When the laboratory adds the Free T₄ test to the blood sample automatically based on an abnormal TSH result, it referred to as “reflex” testing. Although laboratories vary, most report a normal TSH reference range between 0.4-0.5 mU/L on the lower end and 4-5.5 mU/L on the upper end of the range.

A free T ₄ test is used to find out how well your thyroid gland is working. T ₄ is 1 of 2 hormones produced by the thyroid, a butterfly-shaped gland in your neck. There are 2 forms of T ₄. Some T ₄ in your blood is bound to proteins, and some T ₄ circulates freely, or unbound from proteins.

A CBC test measures the total number of white cells in your blood. A different test called a CBC with differential measures the number of each type of these white blood cells. Platelets, which stop bleeding by helping your blood to clot.

A comprehensive metabolic panel (CMP) is a test that measures 14 different substances in your blood. It provides important information about your body’s chemical balance and metabolism. Metabolism is the process of how the body uses food and energy

This test measures the amount of insulin, the hormone that lets cells take in glucose. Glucose, a sugar that comes from food, is the body’s main source of energy. Glucose levels in the blood rise after meals and trigger the pancreas to make insulin and release it into the blood.

A vitamin B-12 level test checks the amount of vitamin B-12 in the blood or urine to gauge the body’s overall vitamin B-12 stores. Vitamin B-12 is necessary for several bodily processes, including nerve function and the production of DNA and red blood cells.

A vitamin D blood test measures the level of 25(OH)D in your blood. Abnormal levels of vitamin D can indicate bone disorders, nutrition problems, organ damage, or other medical conditions.

Both SARS-CoV-2 IgM and IgG antibodies may be detected around the same time after infection. However, while IgM is most useful for determining recent infection, it usually becomes undetectable weeks to months following infection; in contrast, IgG is usually detectable for longer periods.
