A positive CD68 immunohistochemistry usually indicates that a patient may have a disease such as cutaneous true histiocytic lymphoma, granulocytic sarcoma, or mastocytosis.
Immunohistochemistry is used to diagnose disease by applying the principle of antigen-antibody reaction, in which a chemical reaction results in the coloration of a chromogenic agent that labels the antibody to determine the antigen in the tissue cells.CD68 is a cytoplasmic glycoprotein and is usually a more reliable marker for macrophages.
CD68 is generally found in monocytes, granulocytes, macrophages, large lymphocytes, mast cells, etc. CD68 immunohistochemistry can be used in the diagnosis of cutaneous true histiocytic lymphoma, granulocytic sarcoma, mastocytosis and other diseases.
It can be seen that a positive CD68 immunohistochemistry suggests that the patient may have the above mentioned diseases such as cutaneous true histiocytic lymphoma, granulocytic sarcoma, mastocytosis and so on.
If the test result shows positive CD68 immunohistochemistry, the patient should consult a professional doctor in time.
