What is swine flu? Swine flu, also known as the H1N1 virus, is a relatively new strain of an influenza virus that causes symptoms similar to the regular flu. It originated in pigs but is spread primarily from person to person. Like other strains of the flu, H1N1 is highly contagious, allowing it to spread quickly from person to person. A simple sneeze can cause thousands of germs to spread through the air. The virus can linger on tables and surface areas like door knobs, waiting to be picked up. The best means of dealing with swine flu is to prevent [...]
Your body converts the carbohydrates, which you eat into glucose. Glucose testing is primarily done for people with type 1 diabetes, type 2 diabetes, and gestational diabetes. Diabetes is a condition that causes your blood glucose levels to rise. The amount of sugar in your blood is usually controlled by a hormone called insulin. However, if you have diabetes, your body either doesn’t make enough insulin or the insulin produced doesn’t work properly. This causes sugar to build up in your blood. Increased levels of blood sugar can lead to severe organ damage if left untreated. In some cases, blood glucose testing may also be [...]
With August being Womens month, we at Lab24 urge all our ladies to take time out and come in for their Pap Smear test. A Pap smear, also called a Pap test, is a procedure to test for cervical cancer in women. A Pap smear involves collecting cells from your cervix — the lower, narrow end of your uterus that's at the top of your vagina. Detecting cervical cancer early with a Pap smear gives you a greater chance at a cure. A Pap smear can also detect changes in your cervical cells that suggest cancer may develop in the future. [...]
Does this test have other names? Serum myoglobins, myoglobin-serum What is this test? This test measures the amount of a protein called myoglobin in your blood. It's done to help diagnose conditions caused by muscle damage. Myoglobin is found in your heart and skeletal muscles. There it captures oxygen that muscle cells use for energy. When you have a heart attack or severe muscle damage, myoglobin is released into your blood. Myoglobin increases in your blood 2 to 3 hours after the first symptoms of muscle damage. It usually peaks about 8 to 12 hours later. Your kidneys filter your blood [...]
A RAST test is a type of blood test used to test for allergies. These tests, which use radioactivity, have largely been abandoned by doctors in favor of newer, more accurate forms of allergy testing, but some doctors still use them in certain cases. RAST stands for "radioallergosorbent." RAST tests have been a very safe way to test for food allergies, but they are also expensive and are not considered as accurate as food challenges. When Are RAST Tests Used? In the past, RAST tests were often used in combination with skin tests, or in situations when other tests are considered [...]
What is being tested? The full blood count (FBC) is one of the most commonly requested tests and provides important information about the kinds and numbers of cells in the blood: red blood cells, white blood cells and platelets. Abnormalities in any of these types of cells can indicate the presence of important medical disorders. Blood is composed of a variety of living cells that circulate through the heart, arteries and veins carrying nourishment, hormones, vitamins, antibodies, heat and oxygen to the body's tissues. Blood contains three main components — red blood cells, white blood cells, and platelets — suspended in [...]
Lipids are a group of fats and fat-like substances that are important constituents of cells and sources of energy. A lipid panel measures the level of specific lipids in the blood. Two important lipids, cholesterol and triglycerides, are transported in the blood by lipoprotein particles. Each particle contains a combination of protein, cholesterol, triglyceride, and phospholipid molecules. The particles measured with a lipid profile are classified by their density into high-density lipoproteins (HDL), low-density lipoproteins (LDL), and very low-density lipoproteins (VLDL). Monitoring and maintaining healthy levels of these lipids is important in staying healthy. While the body produces the cholesterol needed [...]
CD4 cells are white blood cells called T lymphocytes or T cells that fight infection and play an important role in immune system function. They are made in the thymus gland and they circulate throughout the body in the blood and lymphatic system. CD4 tests measure the number of these cells in the blood and, in conjunction with an HIV viral load test, help assess the status of the immune system in a person who has been diagnosed... Why Get Tested? Most often, this test is done to measure the strength of your immune system if you have been diagnosed with [...]
Viral load is the term used to describe the amount of HIV in your blood. The more HIV there is in your blood (and therefore the higher your viral load), then the faster your CD4 cell count will fall, and the greater your risk of becoming ill because of HIV. Viral load tests measure the amount of HIV’s genetic material in a blood sample. The results of a viral load test are described as the number of copies of HIV RNA in a millilitre of blood. But your doctor will normally just talk about your viral load as a number. How [...]
