What does testing the lymphoproliferative response of mononuclear cells to polyclonal stimulators mean?
Testing the lymphoproliferative response of mononuclear cells involves measuring the ability of these immune cells to proliferate in response to nonspecific stimulators like mitogens or antigens. This test is used to evaluate the overall functionality of the immune system and can help assess immune cell function in various conditions, including immunodeficiency disorders and autoimmune diseases. The results can provide insights into the immune system's ability to mount an effective immune response.
What is an atypical lymphoid infiltrate found on left proximal nose?
An atypical lymphoid infiltrate on the left proximal nose suggests a collection of abnormal lymphocytes in the tissue. This finding could be indicative of various conditions, including lymphoma or other lymphoproliferative disorders. Further evaluation, such as a biopsy and immunohistochemical studies, would be needed to determine the nature of the infiltrate and guide appropriate management.
What does a positive CD30 stain mean in immunochemistry?
A positive CD30 stain in immunochemistry typically indicates the presence of cells expressing CD30 antigen. CD30 is a cell surface marker that is commonly found on activated T cells, B cells, and certain types of lymphoma cells. Therefore, a positive CD30 stain can be suggestive of lymphoproliferative disorders or other conditions associated with abnormal immune cell activation.
Why does blood agglutinate?
Leukoagglutination is extremely rare in health individuals and is far more common in those suffering from infections, sepsis, lymphoproliferative disorders, alcoholic liver disease, hemophilia, and autoimmune diseases.
What is process Lymphopoiesis?
Lymphopoiesis is the process by which lymphocytes, a type of white blood cell crucial for the immune system, are produced and developed from precursor cells in the bone marrow and thymus. This process involves several stages, including the differentiation of hematopoietic stem cells into lymphoid progenitor cells, which further mature into B cells in the bone marrow and T cells in the thymus. Lymphopoiesis is essential for maintaining the body's immune response and ensuring the production of diverse lymphocyte populations capable of recognizing various pathogens. Dysregulation of this process can lead to immunodeficiencies or lymphoproliferative disorders.
What has the author John F Stephens written?

Is there a cure for XLP?
To date (April 2014) there is no cure for X-linked lymphoproliferative disease (XLP); however, research into a cure is being conducted. In one study, allogeneic hematopoietic stem cell transplantation (HSCT) showed promise of curing the disease. To read the study, visit the Related Link.
What is ebv Panel?
Epstein-Barr virus (EBV) is a ubiquitous herpesvirus that affects more than 95% of the world's population and is the causative agent of infectious mononucleosis (IM). It is also associated with Burkitt's lymphoma, nasopharyngeal carcinoma, and lymphoproliferative disorders occurring in primary and acquired immunodeficiency disorders.EBV panel tests for antibodies.

What does it mean to have too much protein in your blood?
Having too much protein in your blood, known as hyperproteinemia, can indicate various underlying health conditions such as dehydration, infections, inflammatory disorders, or multiple myeloma. It is important to determine the underlying cause and work with a healthcare provider to address any potential health issues.
What is Lymphocytes Relative in bloodwook testing mean?
Lymphocytes relative refers to the proportion of lymphocytes in the total white blood cell count during a blood test. Lymphocytes are a type of white blood cell crucial for the immune response, and their relative percentage can provide insight into a person's immune status. An elevated or decreased lymphocyte percentage may indicate various conditions, including infections, autoimmune diseases, or lymphoproliferative disorders. Understanding this value helps healthcare providers assess overall health and diagnose potential issues.
Why does blood agglutinate?
Leukoagglutination is extremely rare in health individuals and is far more common in those suffering from infections, sepsis, lymphoproliferative disorders, alcoholic liver disease, hemophilia, and autoimmune diseases.
Which disease is caused when white blood cells are produced in excess?
There are several. Leukemia and lymphoma are probably the most common, but there are other lymphoproliferative disorders that can cause an uncontrolled production of white blood cells. Other causes of elevated white blood counts include infection, stress, steroid use, and medications (especially medications that cause you to make more white blood cells - like neupogen or neulasta).

What is a hematology lab test ESR for?
-Erythrocyte Sedimentation Rate (ESR) is the rate at which red blood cells precipitate in a period of one hour.-This is a nonspecific test for inflammatory and lymphoproliferative disorders.-To measure ESR, non coagulated blood is placed in an upright tube, the rate at which red blood cells fall is measured and expressed in millimeters per hour.-Normal value of ESR is 3-7 mm/hr-Pro sedimentation factor is fibrinogen and anti sedimentation factor is -ve charge on RBCs.-ESR is raised in pregnancy, rheumatoid arthritis etc. and decreased in polycythemia, sickle cell anemia, hereditary spherocytosis, CHF.
