Description
Blood, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:Â
The test requires a blood sample.
Test Time:Â
Test results are typically available within a few hours to a day.
Test Normal Range:
The normal range for CA (Cyfra) 21-1 levels can vary depending on the laboratory’s reference values.
What is the Test?Â
The CA (Cyfra) 21-1 test measures the level of a protein called cytokeratin 19 fragment (Cyfra 21-1) in the blood. Elevated levels of Cyfra 21-1 can be associated with certain types of cancer, particularly lung cancer.
Test Procedure:
Blood Collection: A blood sample is drawn from a vein, usually from the arm. Laboratory Analysis: The blood sample is sent to a laboratory for analysis to measure the level of Cyfra 21-1.
When to Take the Test:Â
This test may be recommended for individuals who are suspected to have lung cancer or other cancers that can produce elevated levels of Cyfra 21-1.
Who Should Take This Test:
Individuals with symptoms of lung cancer, such as persistent cough, chest pain, or difficulty breathing. Individuals with a history of lung cancer or other cancers associated with elevated Cyfra 21-1 levels
Precautions for Exceptional Cases (Pregnancy etc.):Â
Pregnant individuals should inform their healthcare provider about their pregnancy status before taking the test, as pregnancy can affect test results.
FAQs:
Q1: Can elevated Cyfra 21-1 levels indicate cancers other than lung cancer?
A: While Cyfra 21-1 is often associated with lung cancer, elevated levels can also be seen in other cancers that originate in the lining of certain organs, such as the bladder, esophagus, or cervix.
Q2: Is the CA (Cyfra) 21-1 test used for cancer screening?
A: The CA (Cyfra) 21-1 test is not commonly used for general cancer screening. It is typically used in the diagnostic process for individuals with suspected lung cancer or specific types of cancers.
Q3: What factors can affect Cyfra 21-1 levels?
A: Smoking and certain lung diseases can affect Cyfra 21-1 levels.It’s crucial that you give your doctor your whole medical history.
Q4: Can Cyfra 21-1 levels be elevated in non-cancerous conditions?
A: Yes, elevated levels can occur in non-cancerous lung conditions such as chronic obstructive pulmonary disease (COPD) or lung infections.
Q5: Can the CA (Cyfra) 21-1 test replace other cancer diagnostic tests?
A: The CA (Cyfra) 21-1 test is often used in conjunction with other diagnostic tests, such as imaging scans and biopsies, to help confirm or rule out a cancer diagnosis. It is not used in isolation.
