What is Glucose?

A blood sugar test measures the amount of a sugar called glucose in a sample of your blood. Glucose (also known as blood sugar) is a major source of energy for most cells of the body, including brain cells. Glucose is a building block for carbohydrates. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. Carbohydrates are quickly turned into glucose in your body. This can raise your blood glucose level. A hormone called insulin helps move glucose from your bloodstream into your cells. Elevated fasting blood glucose is often a sign of Type 2 diabetes. Very high glucose levels, whether fasting or not, usually indicate Type 1 diabetes.

Glucose is often part of a regular blood test called the comprehensive metabolic panel (CMP).

The marker Glucose (OA) (Urine) is used to assess the level of glucose in urine, which can provide important insights into an individual's metabolic health. Glucose is a type of sugar that is a primary source of energy for the body's cells. Under normal circumstances, glucose is reabsorbed by the kidneys and does not appear in urine. However, when blood glucose levels are excessively high, as can occur in conditions like diabetes, the kidneys may not be able to reabsorb all of the glucose, leading to its presence in the urine. This condition is known as glycosuria. Monitoring glucose in urine can help detect issues with blood sugar regulation, which may be indicative of diabetes or other metabolic disorders. In addition, the presence of glucose in urine can sometimes signal kidney damage or dysfunction, as the kidneys are not effectively filtering blood. Regularly testing urine for glucose is a non-invasive method that can aid in early detection and management of metabolic conditions, helping individuals maintain better overall health through timely intervention and lifestyle adjustments.

The Glucose - Arterial marker on Labcorp's Arterial Blood Gas (ABG) Panel measures the concentration of glucose in arterial blood. Glucose is a primary energy source for the body's cells and is tightly regulated by hormones such as insulin and glucagon. Monitoring glucose levels is essential for assessing metabolic status and diagnosing conditions like diabetes mellitus and hypoglycemia.

Glucose 6-Phosphate Dehydrogenase, often abbreviated as G6PD (or G-6-PD), plays a critical role in the body's cellular function. This enzyme is vital for the health of all cells, but it's particularly crucial for red blood cells. 

G6PD helps cells manage oxidative stress. Oxidative stress occurs when there's an imbalance between the production of harmful free radicals (unstable molecules that can damage cells) and the body's ability to counteract their harmful effects through neutralization with antioxidants. G6PD aids in the production of NADPH, a molecule that plays a key role in the antioxidant defense system of cells. Specifically, NADPH helps maintain the supply of glutathione, a powerful antioxidant that protects red blood cells from damage.

The importance of G6PD comes into the spotlight when we consider its role in maintaining the integrity and functionality of red blood cells. These cells are responsible for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide back to the lungs for exhalation. Because red blood cells are continuously exposed to oxygen, they are particularly susceptible to oxidative damage. G6PD ensures that red blood cells can protect themselves against such damage and thus, maintain their crucial function in oxygen transportation.

Glucose Non-Fasting tests are an essential tool in the ongoing monitoring and management of blood sugar levels, crucial for individuals with diabetes or those at risk. Unlike traditional glucose tests that require fasting, these non-fasting tests offer a convenient and immediate assessment of blood glucose levels at any time of day, regardless of when you last ate.

Glucose is usually not present in urine, because in the kidneys glucose is reabsorbed from the filtrate of glomerulus, across the tubular epithelium of proximal tubule into the bloodstream.

GLUCOSE-6-PHOSPHATE DEHYDROGENASE helps red blood cells (RBCs) function normally. It also protects them from potentially harmful byproducts that can accumulate when your body is fighting infection or as the result of certain medications. A lack of GLUCOSE-6-PHOSPHATE DEHYDROGENASE may make RBCs more vulnerable to breaking down in a process called hemolysis.

The patient’s cells are challenged with glucose and their ability to grow in the presence or absence of insulin is determined. A significant decrease of cell growth is indicative of reduced ability to metabolize glucose.

Preliminary evidence suggests that persons with abnormal Glucose-Insulin Interaction exhibit hypoglycemia or hyperglycemia based on glucose tolerance testing. Morbidly obese persons with abnormal Glucose-Insulin Interaction may indicate insulin resistance. Thus, deficiency symptoms include fatigue, headaches, nausea, disorientation, dizziness, cold hands and feet, glucose intolerance.

Dietary suggestions are to replace, as much as possible, refined carbohydrates (table sugar, corn syrup, white flour, products made predominantly with white flour and/or sugar) with wholefood, unrefined carbohydrates (whole grain products, legumes, fruits). Reduce intake of foods with a high glycemic index. If clinically indicated, it is suggested that further laboratory testing of glucose and insulin metabolism be conducted (glucose tolerance test, glycosylated hemoglobin). Since chromium status is closely linked with insulin function and glucose tolerance, a chromium deficiency is one possible reason for abnormal Glucose-Insulin Interaction.

Glutamate is a vital neurotransmitter in the central nervous system, involved in almost all significant excitatory brain functions. It is the primary and most abundant excitatory neurotransmitter, and it's estimated that over half of all neural synapses release glutamate, making it a critical player in neural circuit communication.

Glutamic acid and glutamate are essentially interchangeable terms. The two molecules are almost identical, except that glutamic acid has an additional proton, or hydrogen atom. In physiological conditions, glutamic acid sheds this extra proton and becomes glutamate, the abundant form of the amino acid in the human body.

Glutamate is a crucial excitatory neurotransmitter that plays a vital role in maintaining healthy brain and nervous system function. It enables us to learn, remember, feel, sense, and coordinate our movements effectively.

Glutamate functions as the major excitatory neurotransmitter and metabolic fuel throughout the body. Glutamate is produced in your body, and is also found in many foods.

Glutamate is an important marker included on the Amino Acids; Urine 24-hour panel provided by Doctor's Data. This amino acid plays a crucial role in the body, primarily as a neurotransmitter in the brain, where it helps in sending signals between nerve cells. It's one of the most abundant neurotransmitters and is essential for learning and memory. When measured in a urine test, the levels of glutamate can give valuable insights into a person's metabolic processes. Abnormal levels of glutamate in the urine can indicate various health issues. For example, elevated glutamate can suggest problems with neurological functions or an imbalance in amino acid metabolism. On the other hand, low levels might point to issues like inadequate protein intake or specific metabolic disorders. The 24-hour urine collection method used in this test helps to provide a comprehensive view of the glutamate levels over a full day, giving a more accurate assessment than a single snapshot might. This detailed information can be crucial for doctors to diagnose potential health issues and to recommend appropriate dietary adjustments or treatments to balance glutamate levels in the body.

The brain's major excitatory neurotransmitter glutamate (also known as glutamic acid) functions as the "on" switch in the brain. Glutamate regulates appetite, thinking (cognition), increases gut motility, optimizes learning, modulates memory, mood and perception of pain, improves libido, and decreases sleep. The brain is the major contributor of glutamate in the body.

Glutamate is an excitatory neurotransmitter and is considered to be the most abundant neurotransmitter in the nervous system. Glutamate is involved in most aspects of normal brain function including cognition, memory and learning, although high levels of glutamate can cause excitotoxicity, a process where nerve cells are damaged by excessive stimulation.

The Glutamic Acid/Glutamine Ratio is used to identify specimen handling issues that cause spontaneous degradation of glutamine to glutamate, and can reveal the origin of difficulty maintaining systemic pH balance.

Glutamic acid is a nonessential amino acid is derived from the diet and from the breakdown of gut proteins. Glutamate is a major excitatory neurotransmitter in the brain. It plays a role in neuronal differentiation, migration, and survival in the developing brain. It is also involved in synaptic maintenance, neuroplasticity, learning, and memory.
