Hepatitis C Antibody, HCV RNA & Liver Panel Most Popular

The Hepatitis C Antibody, HCV RNA & Liver Panel panel contains 3 tests with 14 biomarkers.

Hepatitis C Antibody, HCV RNA & Liver Panel

  • Hepatitis C Antibody
  • Hepatitis C Virus RNA, Quantitative, Real-Time PCR
  • Hepatic Function Panel

Hepatitis C antibody tests are used to screen individuals for the infection, including, people with no signs or symptoms but with risk factors, people who have symptoms associated with hepatitis or liver disease, or those who have been exposed to the virus.

Since the antibody test can remain positive for most people even if they have cleared the infection, this panel includes a hepatitis C RNA test, which detects the genetic material of the virus. A positive result on the RNA test means the virus is present, the infection has not resolved, and the person may require treatment. The liver panel is included to assess the health of the liver.

An HCV antibody test is typically reported as "positive" or "negative."

Results of Hepatitis C Virus RNA testing are reported as a number if virus is present. If no virus is present or if the amount of virus is too low to detect, the result is often reported as "negative" or "not detected."

Interpretation of the HCV screening and follow-up tests is shown below. In general, if the HCV antibody test is positive, then the individual tested is infected or has likely been infected at some time with hepatitis C. If the Hepatitis C Virus RNA test is positive, then the person has a current infection. If no Hepatitis C Virus RNA is detected, then the person either does not have an active infection or the virus is present in very low numbers.

HCV Antibody = Negative

No infection or too early after exposure for the test to be accurate; if suspicion remains high, retesting at a later time may be required.

_________________________

HCV Antibody = Positive or Indeterminate

HCV RNA = Negative

Past infection or no infection (false-positive screen); additional testing if indicated

Also known as: LFTs, Liver Function Tests, Liver Panel

Albumin

Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood.

Albumin/Globulin Ratio

The ratio of albumin to globulin (A/G ratio) is calculated from measured albumin and calculated globulin (total protein - albumin). Normally, there is a little more albumin than globulins, giving a normal A/G ratio of slightly over 1. Because disease states affect the relative amounts of albumin and globulin, the A/G ratio may provide a clue as to the cause of the change in protein levels. A low A/G ratio may reflect overproduction of globulins, such as seen in multiple myeloma or autoimmune diseases, or underproduction of albumin, such as may occur with cirrhosis, or selective loss of albumin from the circulation, as may occur with kidney disease (nephrotic syndrome). A high A/G ratio suggests underproduction of immunoglobulins as may be seen in some genetic deficiencies and in some leukemias. More specific tests, such as liver enzyme tests and serum protein electrophoresis, must be performed to make an accurate diagnosis. With a low total protein that is due to plasma expansion (dilution of the blood), the A/G ratio will typically be normal because both albumin and globulin will be diluted to the same extent.

Alkaline Phosphatase

Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with higher amounts of ALP include the liver, bile ducts, and bone.

Alt

Alanine transaminase (ALT) is an enzyme found in the highest amounts in the liver. Injury to the liver results in release of the substance into the blood.

AST

AST (aspartate aminotransferase) is an enzyme found in high amounts in liver, heart, and muscle cells. It is also found in lesser amounts in other tissues.

Bilirubin, Direct

Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool.

Bilirubin, Indirect

Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool.

Bilirubin, Total

Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool.

Globulin

Globulins is the collective term for most blood proteins other than albumin. Identifying the types of globulins can help diagnose certain disorders. Globulins are roughly divided into three groups: alpha, beta, and gamma globulins. Gamma globulines include various types of antibodies such as immunoglobulins (Ig) M, G, and A.

Protein, Total

The total protein is the total amount of two classes of proteins, albumin and globulin that are found in the fluid portion of your blood. Proteins are important parts of all cells and tissues. Your albumin helps prevent fluid from leaking out of blood vessels and your globulins are an important part of your immune system.

Also known as: Anti HCV, HCV Antibody

Hepatitis C Antibody

The Hepatitis C Antibody Test, sometimes called the Anti-HCV Test, looks for antibodies to the Hepatitis C virus. Antibodies are chemicals released into the bloodstream when someone gets infected.
