Glutathione is an antioxidant, a type of chemical which helps to boost your immune system as well as prevent and reverse cellular damage.  Unlike most antioxidants which come from the food you eat, glutathione is naturally produced by the body in the liver. Glutathione plays a number of roles in overall health including boosting the immune system, helping to break down nutrients in food, and protecting against chronic diseases such as Alzheimer's, Parkinsons, diabetes, some types of cancer, and heart disease.

The Total IgA biomarker on the 1018 Celiac Profile - Serum by Genova Diagnostics measures the overall levels of Immunoglobulin A (IgA), an essential antibody that plays a crucial role in the immune system, particularly at mucosal surfaces like the gastrointestinal tract. IgA protects against pathogens and dietary antigens, such as gluten, which are processed in the gut. In the context of celiac disease testing, Total IgA is measured to ensure the accuracy of IgA-dependent biomarkers, such as anti-tissue transglutaminase (tTG IgA) and deamidated gliadin peptide (DGP IgA).

What is Total IgA?

Total IgA measures the concentration of Immunoglobulin A in the blood, an antibody that plays a crucial role in immune defense—particularly in the mucous membranes of the respiratory, gastrointestinal, and urogenital tracts. It is the body’s first line of defense against inhaled, ingested, and sexually transmitted pathogens.

Why is Total IgA important?

IgA provides immune protection by neutralizing viruses and bacteria before they penetrate deeper into the body. It is also involved in maintaining a healthy balance of immune tolerance in the gut. Abnormal IgA levels can signal underlying immune disorders or chronic inflammatory conditions.

What is Total IgG?

Total IgG measures the concentration of Immunoglobulin G, the most abundant antibody in the bloodstream. IgG plays a central role in long-term immune protection by recognizing and neutralizing viruses, bacteria, and other foreign invaders. It also helps the immune system "remember" past infections, providing immunity over time.

Why is Total IgG important?

IgG is essential for fighting infections and for the effectiveness of vaccinations. It circulates in the blood and tissues, identifying pathogens and helping to trigger a broader immune response. Total IgG measurement provides insight into the strength and status of your adaptive immune system.

Total insulin is a critical marker used to measure the overall insulin levels in the bloodstream, which can provide valuable insights into a person's metabolic health. Insulin is a hormone produced by the pancreas that plays a vital role in regulating blood sugar levels by facilitating the uptake of glucose into cells. By assessing total insulin levels, healthcare professionals can determine how effectively the body is responding to glucose and insulin, which is essential for diagnosing and managing conditions like diabetes, insulin resistance, and metabolic syndrome. Elevated total insulin levels can indicate insulin resistance, where the body's cells are less responsive to insulin, often leading to high blood sugar levels and, eventually, type 2 diabetes. Conversely, low insulin levels can point to conditions such as type 1 diabetes, where the pancreas produces little or no insulin. Monitoring total insulin is crucial for understanding an individual's risk for these conditions and for tailoring appropriate dietary, lifestyle, and medical interventions to maintain optimal health. Regular monitoring can help detect early changes in insulin sensitivity, enabling timely interventions to prevent the progression of metabolic disorders.

Total iron-binding capacity (TIBC) is a blood test to see if you have too much or too little iron in the blood. Iron is vital in that it transports oxygen around the body. Frequently, a TIBC is ordered along with several other tests to determine the cause of conditions like anemia or to assess blood health in general.

Total Lactobacilli measured in x10^3 CFU/g (Colony Forming Units per gram) is a critical biomarker indicating the presence and abundance of beneficial Lactobacillus bacteria in the gastrointestinal tract. These gram-positive bacteria are key contributors to the gut microbiome, supporting both digestive and overall health.

Clinicians use Total Lactobacilli levels to assess the state of beneficial bacteria in the gut ecosystem. Healthy levels are associated with improved digestive function and immune health, while low levels may signal an imbalance in the gut microbiome, also known as dysbiosis.

Total Memory CD27+ % is a key measurement in B cell subset analysis that indicates the proportion of memory B cells within the B cell population. CD27, a tumor necrosis factor receptor family member, serves as a reliable marker for memory B cells and signifies previous antigen exposure and successful immune responses. When measured as a percentage of CD19+ B cells, the typical range in healthy adults is 25-45%. The analysis includes both switched (IgD-CD27+) and non-switched (IgD+CD27+) memory B cells. This marker is clinically significant for assessing various immunological conditions such as Common Variable Immunodeficiency (CVID), autoimmune diseases, and immunosenescence, as well as monitoring treatment responses and immune reconstitution. The percentage typically varies with age, with older adults showing higher values due to accumulated antigen exposure, while younger individuals generally have lower percentages as they are still developing their immunological memory.

The Total Memory CD27+ Absolute Count (Abs) measures the number of CD27+ memory T cells in the bloodstream, critical for adaptive immunity and rapid responses to previously encountered pathogens. CD27, a co-stimulatory receptor, is expressed on naive and memory T cells but absent in terminal effector T cells. This marker is significant for assessing immune competence, diagnosing immunodeficiencies (e.g., CVID, HIV/AIDS), monitoring chronic infections (e.g., hepatitis, CMV), autoimmune diseases, and immune recovery after treatments like chemotherapy or transplantation. Abnormal levels may indicate immune dysfunction, active infections, or chronic immune activation. Interpretation should consider clinical context, other immune markers, and additional testing to guide diagnosis and treatment.

The Total Monounsaturated Fats marker provides valuable information about the level of monounsaturated fats in your body. Monounsaturated fats are a type of healthy fat found in various foods, including olive oil, avocados, nuts, and seeds. These fats are known for their beneficial effects on heart health, as they can help reduce bad cholesterol levels and lower the risk of heart disease.

Total NK cells (CD56+) represent a critical subset of lymphocytes pivotal for innate immunity, providing the first line of defense against tumors and a variety of pathogens. Natural Killer (NK) cells are characterized by their expression of the CD56 surface marker, distinguishing them from other lymphocyte subsets. The significance of measuring Total NK cells (CD56+) in this panel lies in their role in immune surveillance and early immune responses.

In a lymphocyte panel, which is a key tool for evaluating the immune system, Total NK (Natural Killer) cells identified by CD16 and CD56 surface markers play a significant role. NK cells are a distinct subset of lymphocytes, essential for innate immune responses, especially in the early defense against viral infections and tumor cells. These cells are unique as they do not require prior sensitization to recognize and attack abnormal cells. The lymphocyte panel typically measures various lymphocyte populations, including T cells, B cells, and NK cells, to assess immune function and identify potential disorders.

In clinical and diagnostic settings, assessing Total NK cells is important for understanding a patient's immune status. Abnormalities in NK cell numbers or function can be indicative of various conditions, such as immune deficiencies, autoimmune diseases, certain cancers, and responses to viral infections. Therefore, the lymphocyte panel, including the analysis of Total NK cells, is a vital diagnostic tool, helping in the diagnosis, monitoring, and management of a range of immune-related disorders. It also plays a role in the assessment of patients undergoing treatments that affect the immune system, such as chemotherapy, radiation therapy, or immunotherapy, providing crucial information for optimizing treatment strategies.
