What is an analyte test?

An analyte is a substance or chemical constituent that is determined in an analytical procedure, such as a titration. In medicine, analyte often refers to the type of test being run on a patient, as the test is usually determining a chemical substance in the human body.

What are the 3 levels of CLIA testing?

Current Regulation: CLIA established three categories of tests: waived tests, moderate complexity tests, and high complexity tests.

What is the basic problem with automatic analyzer *?

Disadvantages: -The machine does not allow test selection; all tests must be performed even if not requested. -The machine must run continuously even when there are no tests. -Because of the continuous flow, reagents must be drawn at all times even when there are no tests to perform; which results in reagent wasting.

What is automated chemistry analyzer?

An automated analyser is a medical laboratory instrument designed to measure different chemicals and other characteristics in a number of biological samples quickly, with minimal human assistance. These measured properties of blood and other fluids may be useful in the diagnosis of disease.

What is the function of analyzer?

An analyser or analyzer is a tool used to analyze data. For example, a gas analyzer tool is used to analyze gases. It examines the given data and tries to find patterns and relationships. An analyser can be a piece of hardware or software.

How does a chemistry analyzer work?

They are used to determine the concentration of certain metabolites, electrolytes, proteins, and/or drugs in samples of serum, plasma, urine, cerebrospinal fluid, and/or other body fluids. Samples are inserted in a slot or loaded onto a tray, and tests are programmed via a keypad or bar-code scanner.

What is dry chemistry analyzer?

Dry chemistry analyzers comprise highly sensitive multilayered reagent coated slides instead of wet reagents. It requires only 10 ml to 50 ml of sample. The results of dry chemistry analyzers are comparable to conventional wet chemistry analyzers.

What is the principle of semi auto Analyser?

Though in either case, a Semi-Automatic biochemistry analyzer follows the Colorimetry, Photometry, and Absorbance principles for working under the optical techniques. While it follows the working of direct potentiometry and indirect potentiometry principles under the category of electrochemical techniques.

What is the purpose of clinical chemistry?

Clinical chemistry uses chemical processes to measure levels of chemical components in body fluids and tissues. The most common specimens used in clinical chemistry are blood and urine. Many different tests exist to detect and measure almost any type of chemical component in blood or urine.

What is the purpose of blood chemistry test?

A test done on a sample of blood to measure the amount of certain substances in the body. These substances include electrolytes (such as sodium, potassium, and chloride), fats, proteins, glucose (sugar), and enzymes.

Why is serum preferred over plasma in clinical chemistry?

In general, serum samples (red top tubes) are preferred for chemistry testing. This is because our chemistry reference intervals are based on serum not plasma. For example, LDH, potassium and phosphate are higher in serum than plasma, because of release of these constituents from cells during clotting.

What three enzymes are useful in diagnosing liver disease?

This test measures the total amount of protein in the blood. ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), and gamma-glutamyl transpeptidase (GGT). These are different enzymes made by the liver. Bilirubin, a waste product made by the liver.

What are the symptoms of poor liver function?


  • Skin and eyes that appear yellowish (jaundice)
  • Abdominal pain and swelling.
  • Swelling in the legs and ankles.
  • Itchy skin.
  • Dark urine color.
  • Pale stool color.
  • Chronic fatigue.
  • Nausea or vomiting.

What is the best test for liver function?

The ALT and AST tests measure enzymes that your liver releases in response to damage or disease. The albumin test measures how well the liver creates albumin, while the bilirubin test measures how well it disposes of bilirubin. ALP can be used to evaluate the bile duct system of the liver.

Can liver damage be detected in a blood test?

Blood tests used to assess the liver are known as liver function tests. But liver function tests can be normal at many stages of liver disease. Blood tests can also detect if you have low levels of certain substances, such as a protein called serum albumin, which is made by the liver.

What can show up in a standard blood test?

A typical routine blood test is the complete blood count, also called CBC, to count your red and white blood cells as well as measure your hemoglobin levels and other blood components. This test can uncover anemia, infection, and even cancer of the blood.

Does alcohol affect lab results?

These include: Alcohol: Alcohol can also affect blood sugar and fat levels, giving inaccurate results to blood tests that require fasting. If a person is being asked to fast before a blood test, they should also refrain from drinking alcohol. Smoking: Smoking can also affect blood test results.
