Cancer Screening Tumor Markers
AFP
AFP is used as a tumor marker to help detect and diagnose cancers of the liver, testes, and ovaries. Though the test is often ordered to monitor people with chronic liver diseases such as cirrhosis, chronic hepatitis B or hepatitis C because they have an increased lifetime risk of developing liver cancer. If a person has been diagnosed with hepatocellular carcinoma or another form of AFP-producing cancer, an AFP test may be ordered periodically to help monitor the person's response to therapy and to monitor for cancer recurrence.
AFP-L3
An AFP-L3 is sometimes also ordered to compare the amount of the AFP variant called AFP-L3 to the total amount of AFP. The test is used to help evaluate the risk of developing hepatocellular carcinoma, especially in those with chronic liver disease, and also to evaluate response of hepatocellular carcinoma to treatment.
Amylase
Amylase is a blood test that is used to measure the amount of amylase in the blood’s serum. It is used to assess for and detect a pancreatic disorder.
CA 125
The Cancer Antigen 125 (CA-125) test measures the amount of CA-125 in the blood. CA-125 is a protein that is present on the surface of most, but not all, ovarian cancer cells. This makes the test useful as a tumor marker in specific circumstances. Significantly elevated concentrations of CA-125 may be present in the blood of a woman who has ovarian cancer. Small quantities of CA-125 are produced by normal tissues throughout the body and by some other cancers. Levels in the blood may be moderately elevated with a variety of non-cancerous conditions, including menstruation, pregnancy, and pelvic inflammatory disease.
CA 15-3
Cancer antigen 15-3 (CA 15-3) is a protein that is produced by normal breast cells. In many people with cancerous breast tumors, there is an increased production of CA 15-3 and the related cancer antigen 27.29. CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the bloodstream, making it useful as a tumor marker to follow the course of the cancer. CA 15-3 is elevated in only about 10% of women with early localized breast cancer but is elevated in about 80% of those with metastatic breast cancer. CA 15-3 may also be elevated in healthy people and in individuals with other cancers (e.g., colon, lung, pancreas, ovary, or prostate malignancies) or certain conditions (e.g., cirrhosis, hepatitis, and benign breast disease).
CA 19-9
Cancer antigen 19-9 (CA 19-9) is a protein that exists on the surface of certain cancer cells. CA 19-9 does not cause cancer; rather, it is shed by the tumor cells, making it useful as a tumor marker to follow the course of the cancer. CA 19-9 is elevated in 70% to 95% of people with advanced pancreatic cancer, but it may also be elevated in other cancers, conditions, and diseases such as colorectal cancer, lung cancer, gallbladder cancer, bile duct obstruction (e.g., gallstones), pancreatitis, cystic fibrosis, and liver disease. Small amounts of CA 19-9 are present in the blood of healthy people.
CA 27.29
CA 27.29 may be useful for monitoring patients for metastatic breast cancer.
Calcitonin
Calcitonin concentration is increased in patients with medullary thyroid carcinoma. Calcitonin concentrations may be used to monitor disease.
CEA
The CEA test measures the level of carcinoembryonic antigen (CEA) in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.

A Comprehensive Metabolic Panel or CMP is a blood test that is a combination of a Basic Metabolic Panel, a Liver Panel, and electrolyte panel, and is used to screen for, diagnose, and monitor a variety of conditions and diseases such as liver disease, diabetes, and kidney disease.
Culture, Urine, Routine (REFLEX)
A Urine Culture test is a test that is used to identify bacteria or foreign organisms in urine and test for antibiotic susceptibilities.
DCP (Des-Gamma-Carboxy-Prothrombin)
The DCP assay is intended for in vitro diagnostic use as an aid in the risk assessment of patients with chronic liver disease for progression to hepatocellular carcinoma (HCC) in conjunction with other laboratory findings and clinical assessment.
Fecal Globin by Immunochemistry
Fecal Globulin by immunochemistry is a test that measures the amount of blood present in fecal samples. The results from the fecal globulin test can be used to detect a lower gastrointestinal disorder. It is recommended to be a part of the routine physical examination.
Screen for lower gastrointestinal bleeding associated with colorectal cancer, adenomas, polyps, and other lower gastrointestinal conditions
Gastrin
For the diagnosis and monitoring of gastrin-secreting tumors, gastric ulcer, Zollinger-Ellison syndrome. Increased in pernicious anemia.
hCG, Total, Quantitative
The hCG test is a blood test that measures the amount of hCG in the blood. It is used to confirm pregnancy or to help identify an ectopic pregnancy. It can also be used to confirm that there is not a pregnancy before a medical treatment.
Lactate Dehydrogenase (LD) (LDH)
LDH isoenzymes is a test to check how much of the different types of lactate dehydrogenase (LDH) are in the blood. Measurement of LDH isoenzymes helps determine the location of any tissue damage. LDH is found in many body tissues such as the heart, liver, kidney, skeletal muscle, brain, blood cells, and lungs. LDH exists in 5 forms, which differ slightly in structure. LDH-1 is found primarily in heart muscle and red blood cells. LDH-2 is concentrated in white blood cells. LDH-3 is highest in the lung. LDH-4 is highest in the kidney, placenta, and pancreas. LDH-5 is highest in the liver and skeletal muscle.
PSA, Free and Total
PSA stands for prostate-specific antigen. It is a protein produced by prostate cells. The PSA test is done to help diagnose and follow prostate cancer in men.
PSA Free and Total is a test that is used to measure the total amount of PSA in the blood along with the amount of free PSA. There are two types of PSA, complex and free. This test is used to measure both and to calculate the PSA ratios.

Chromogranin A, LC/MS/MS
Chromogranin A, LC/MS/MS - Chromogranin-A (CgA) is an acidic glycoprotein expressed in the secretory granules of most normal and neoplastic neuroendocrine (NE) cell types, where it is released together with peptide hormones and biogenic amines. Neuroendocrine tumors (NETs) are a form of cancer that differ from other neoplasia in that they synthesize, store, and secrete peptides, e.g., CgA and amines. CgA is secreted from neuroendocrine-derived tumors including foregut, midgut and hindgut gastrointestinal NETs, pheochromocytomas, neuroblastomas, medullary thyroid carcinomas, some pituitary tumors, functioning and non-functioning pancreatic NETs.
Significantly elevated CgA levels have been found in patients with other diseases, such as impaired renal function, untreated benign essential hypertension, gastritis, prostatic carcinoma, and hyperparathyroidism. The best-characterized circulating biomarker that identifies NETs in general is CgA. Monitoring blood CgA levels may effectively provide information that is helpful in delineating tumor burden and rate of tumor growth, predicting tumor response to therapy and providing some indication as to prognosis.
Protein Total And Protein Electrophoresis W Refl
Protein electrophoresis is a test that measures specific proteins in the blood. The test separates proteins in the blood based on their electrical charge. The protein electrophoresis test is often used to find abnormal substances called M proteins.
