Description
Blood, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
For the Immunohistochemistry (5 Markers) test, a tissue sample is required. This tissue sample is typically obtained through a biopsy or surgical procedure.
Test Time:
The test time for Immunohistochemistry (IHC) can vary depending on the laboratory and the specific markers being tested. It usually takes several days to process and interpret the results.
Test Normal Range:
Immunohistochemistry does not have a traditional “normal range” like some blood tests. Instead, it involves the evaluation of specific protein markers within tissue samples to assist in the diagnosis and classification of diseases.
What is the Test?
Immunohistochemistry is a laboratory technique used to detect specific proteins (antigens) in tissue samples. In the case of the Immunohistochemistry (5 Markers) test, it simultaneously assesses the presence and distribution of five specific protein markers within the tissue. These markers are often associated with various diseases, including cancers.
Test Procedure:
A tissue sample is collected through a biopsy or surgical procedure. The tissue sample is prepared by embedding it in paraffin wax and sectioning it into very thin slices. These tissue sections are then exposed to antibodies labeled with a visible stain. If the specific proteins of interest are present in the tissue, the antibodies will bind to them and produce a visible color change, indicating their presence and location.
When to Take the Test:
The Immunohistochemistry (5 Markers) test is typically ordered by a healthcare provider when a tissue sample needs to be analyzed to aid in the diagnosis and classification of diseases, especially cancer.
Who Should Take This Test:
Patients who have undergone a biopsy or surgery, or those suspected of having certain medical conditions, may be candidates for this test. The test is commonly used to evaluate tissue samples for cancer markers.
Precautions for Exceptional Cases:
In exceptional cases such as pregnancy, the appropriateness of undergoing a biopsy or surgical procedure should be discussed with a healthcare provider. The decision to proceed with any medical procedure during pregnancy will depend on the specific circumstances and risks involved.
FAQs (Frequently Asked Questions):
Q1: Why is Immunohistochemistry performed?
A: Immunohistochemistry is performed to detect specific proteins in tissue samples. It helps diagnose diseases, especially cancer, and provides information about the characteristics and behavior of tissues.
Q2: Is the test painful?
A: The test itself is performed in a laboratory on tissue samples and is not painful. However, the procedure to obtain the tissue sample (biopsy or surgery) may cause some discomfort, but anesthesia is typically used to minimize pain.
Q3: What can the results of the Immunohistochemistry test reveal?
A: The results can reveal the presence or absence of specific proteins in tissue samples. This information is valuable for diagnosing diseases, including different types of cancer, and determining treatment approaches.
Q4: How long does it take to get the results of the Immunohistochemistry test?
A: The time to receive results can vary, but it often takes several days. The tissue samples need to be processed, stained, and analyzed by a pathologist.
Q5: Are there any risks associated with the test?
A: The main risks are associated with the biopsy or surgical procedure needed to obtain the tissue sample. These risks can include bleeding, infection, and discomfort. Before the operation, discuss any concerns you have with your healthcare professional.
