On Demand Medical Testing

The alanine aminotransferase (ALT) blood test is typically used to detect liver injury. It is often ordered in conjunction with aspartate aminotransferase (AST) or as part of a liver panel to screen for and/or help diagnose liver disease

The alkaline phosphatase test (ALP) is used to help detect liver disease or bone disorders.

The BMP includes:

Glucose

Calcium .

Electrolytes

Sodium

Potassium

CO2 (carbon dioxide, bicarbonate)

Chloride

Kidney Tests

BUN (blood urea nitrogen)

Creatinine

Blood calcium is tested to screen for, diagnose, and monitor a range of conditions relating to the bones, heart, nerves, kidneys, and teeth. Blood calcium levels do not directly tell how much calcium is in the bones, but rather, how much calcium is circulating in the blood.

A Complete Blood Count or CBCis a great test to take to give you a snapshotyour health. This test gives important information about the kind and the number of cells in your blood. Physicians use this information to evaluate symptoms, help diagnose conditions and treat certain illnesses (like infections).

Helicobacter pyloritests are used to detect a Helicobacter pylori (H. pylori) infection in the stomach and upper part of the small intestine (duodenum). H. pylori can cause peptic ulcers. But most people with H. pylori in their digestive systems do not develop ulcers. Blood antibody test. A blood test checks to see whether your body has made antibodies to H. pylori bacteria. If you have antibodies to H. pylori in your blood, it means you either are currently infected or have been infected in the past.

A liver (hepatic) function panel is a blood test to check how well the liveris working. This test measures the blood levels of total protein, albumin, bilirubin, and liver enzymes. High or low levels may mean that liver damage or disease is present.

The liver serves several important functions in the body, including changing nutrients into energy for the body and breaking down toxic substances.

Your doctor may order a liver function panel if you have symptoms of liver disease. These symptoms include fever, vomiting, abdominal pain, yellowing of your eyes or skin (jaundice), dark yellow urine, and feeling very tired. This blood test also may be done if you have recently been exposed to a hepatitis virus or are taking a medicine that may cause liver damage.

Hepatitis A virus (HAV) test is a blood test that looks for proteins (antibodies) made by the body in response to the virus that causes hepatitis A. These proteins will be present in your blood if you have a hepatitis A infection now or have had one in the past. It is important to identify the type of hepatitis virus causing the infection to prevent it from spreading and to start the proper treatment.

Hepatitis B e-antigen (HBeAg)is an HBV protein that is only present during an active HBV infection. This test determines how contagious you are. Testing for this antigen can also be used to monitor the effectiveness of treatment for HBV.

Hepatitis B surface antibody (HBsAb)usually appears about 4 weeks after HBsAg disappears. The presence of this antibody means that the infection is at the end of its active stage and you cannot pass the virus to others (you are no longer contagious). This antibody also protects you from getting HBV again in the future. The test is done to determine the need for vaccination—the antibody will be present after receiving the HBV vaccine series, showing that you have protection (immunity) from the virus. Occasionally your test may show that you have both the HBsAb antibodies and HBsAg antigen. In this case you are still contagious.

HCV RIBA is an additional test that detects antibodies to HCV. This test can tell whether a positive result was caused by an actual HCV infection or whether the result was a false-positive. This test may be done to double-check a positive EIA test result.

Elevations in serum lactate dehydrogenase occur from myocardial infarction, liver disease, pernicious and megaloblastic anemia, pulmonary emboli, malignancies, and muscular dystrophy. 

Leptin is an adipocyte-derived hormone that is essential for normal body weight regulation. Leptin production is under neuroendocrine control so that serum concentrations vary directly with the amount of triglycerides stored in adipose tissue depots.

A lipase test measures the amount of this enzyme in a blood sample. High amounts of lipase may be found in the blood when the pancreas is damaged or when the tube leading from the pancreas (pancreatic duct) to the beginning of the small intestine is blocked.

A lipid panel is a blood test that measures lipids—fats and fatty substances used as a source of energy by your body. Lipids include cholesterol, triglycerides, high-

Prealbumin is decreased in protein-calorie malnutrition, liver disease, and acute inflammation. It may be used as an indicator of nutritional requirements and response to therapy during total parenteral nutrition and as a biochemical marker of nutritional adequacy in premature infants.

Screening test for abnormalities of coagulation factors that are involved in the extrinsic pathway. Also used to monitor effects of Warfarin therapy and to study patients with hereditary and acquired clotting disorders.

Albumin, BUN/Creatinine Ratio (calculated), Calcium, Carbon Dioxide, Creatinine, Estimated Glomerular Filtration Rate (calculated), Glucose, Phosphate (as Phosphorus), Potassium, Sodium, Urea Nitrogen

Selenium is an element of parenteral nutrition. Monitoring the Selenium concentration is useful in assessing parenteral nutrition, especially recent intake. Concentrations are also monitored in children with proprionic acidemia who require special diets with supplements.

A urine test checks different components of urine, a waste product made by the kidneys. A regular urine test may be done to help find the cause of symptoms. The test can give information about your health and problems you may have.

The kidneys take out waste material, minerals, fluids, and other substances from the blood to be passed in the urine. Urine has hundreds of different body wastes. What you eat, drink, how much you exercise, and how well your kidneys work can affect what is in your urine.
