Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
Cerebrospinal fluid (CSF) sample collected via lumbar puncture.
Test Time:
Typically, the test results are available in a few days.
Test Normal Range:
Beta HCG is typically not detectable in the cerebrospinal fluid of healthy individuals. Detectable levels may indicate abnormal conditions.
What is the Test?
The Beta HCG CSF test measures the levels of beta human chorionic gonadotropin (HCG) in the cerebrospinal fluid. Beta HCG is a hormone produced during pregnancy, and its presence in the CSF can indicate certain medical conditions, such as certain types of cancer.
Test Procedure:
A lumbar puncture (spinal tap) is performed to collect a small amount of cerebrospinal fluid.The collected CSF sample is sent to a laboratory for analysis.
When to Take the Test:
This test is usually ordered when a healthcare provider suspects or wants to rule out conditions such as certain types of cancer (e.g., germ cell tumors) that can lead to elevated levels of beta HCG in the cerebrospinal fluid.
Who Should Take This Test:
Individuals with suspected or diagnosed medical conditions that may be associated with elevated beta HCG levels in the cerebrospinal fluid may undergo this test.
Precautions for Exceptional Cases (Pregnancy etc.):
If you are pregnant, it is important to inform your healthcare provider before undergoing this test, as beta HCG is a hormone produced during pregnancy and its presence in CSF is abnormal.
FAQs:
Q1: Why is beta HCG measured in cerebrospinal fluid?
A: Elevated beta HCG levels in CSF can indicate the presence of certain types of cancer, especially germ cell tumors.
Q2: Can this test confirm pregnancy?
A: No, this test is not used to confirm pregnancy. Beta HCG in CSF is associated with certain medical conditions.
Q3: How is the cerebrospinal fluid collected for the test?
A: Cerebrospinal fluid is collected through a procedure called lumbar puncture, also known as a spinal tap.
Q4: What other conditions can cause elevated beta HCG levels in CSF?
A: Aside from germ cell tumors, other conditions like testicular cancer and some neurological disorders can lead to elevated levels.
Q5: Is fasting required before the test?
A: Fasting is not typically required for this test. However, heed any specific guidelines provided by your healthcare professional.
