Fasting Blood Glucose · Nüchternblutzucker · FBG · Blutzucker
Fasting Blood Glucose quantifies the concentration of glucose in the blood after a period of fasting.
Fasting is required for accurate measurement. Slight variations may exist based on age and sex.
Fasting Blood Glucose (FBG), also known as Nüchternglukose, is a critical biomarker that measures the concentration of glucose in the blood after a period of fasting, typically 8-12 hours. It provides an immediate snapshot of glucose metabolism and is a fundamental test for assessing glycemic control. Researchers have found that FBG is crucial in diagnosing and monitoring diabetes mellitus, a condition characterized by chronic hyperglycemia. Elevated FBG levels are indicative of impaired glucose regulation and are associated with an increased risk of diabetes-related complications, including neuropathy, cardiovascular diseases, and nephropathy. In the context of athletic performance and biohacking, maintaining optimal fasting glucose levels is essential for metabolic efficiency and energy management. Athletes may monitor FBG to optimize carbohydrate intake and insulin sensitivity, which can enhance endurance and recovery. Biohackers often track FBG as part of a broader strategy to improve longevity and prevent metabolic disorders. However, several factors can influence FBG measurements, including stress, illness, and certain medications. It is crucial to conduct the test under standardized conditions, typically in the morning after an overnight fast, to ensure accuracy. Researchers emphasize the importance of considering these confounders when interpreting FBG results to avoid misdiagnosis or unnecessary interventions.
Klinische Bedeutung
Elevated FBG levels suggest impaired glucose metabolism, often indicative of prediabetes or diabetes. Low FBG levels may indicate hypoglycemia, which can be due to excessive insulin or insufficient carbohydrate intake.
Progressively rising FBG suggests worsening glycemic control, potentially indicating the onset of diabetes. Re-test in 4 weeks if values are outside the optimal range.
Falling FBG values may indicate improved insulin sensitivity or potential hypoglycemia if too low.
Re-test Interval
4 weeks if outside optimal range
Note:
Consult a healthcare provider before starting any supplementation, especially if on medication.
Conduct test in the morning after an overnight fast for consistency.
Testing Frequency
Annually for healthy adults, more frequently if at risk for diabetes.
Correlated with
Current research suggests that reference ranges for fasting blood glucose may vary significantly across different populations, and optimal targets for glycemic control in specific patient groups remain debated. Researchers have not yet established the impact of confounding factors such as age, sex, and ethnicity on fasting blood glucose levels. Additionally, clinical questions regarding the long-term implications of fasting blood glucose variability on diabetes complications and cardiovascular risk remain unanswered.

Researchers found that glycated hemoglobin (HbA1c) is a reliable biomarker for diagnosing diabetes, reflecting long-term glycemic control. This study highlights that elevated HbA1c levels correlate with the risk of diabetes complications, including coronary heart disease and stroke.
Researchers found that hospitalized COVID-19 patients with diabetes who used metformin had significantly lower in-hospital mortality compared to those who did not. Both groups had similar fasting blood glucose levels at admission, but metformin users maintained effective glucose control. This suggests metformin may provide benefits in managing diabetes during COVID-19.
This study examined the prevalence and causes of peripheral neuropathy, which affects 1% to 7% of the general population, especially those over 50. Researchers found that diabetes mellitus, nerve compression, and nutritional deficiencies are common causes. Initial laboratory evaluations, including fasting blood glucose, are crucial for diagnosis.
Researchers found that histidine supplementation can improve markers of glucose homeostasis, including fasting blood glucose. The study highlights the need for more research on the effects of histidine intake and its potential benefits for metabolic health.
Researchers reviewed the triglyceride-glucose (TyG) index as a biomarker for insulin resistance, highlighting its computation from fasting blood glucose and triglycerides. The study discusses its relevance in assessing metabolic syndrome and cardiovascular disease.
This study identified several lipid biomarkers associated with metabolic traits, including fasting blood glucose. Researchers found that specific lipid species were linked to obesity and dysglycemia, suggesting their potential utility in assessing metabolic risk.
This report discussed serum ferritin's dual role as an iron status measure and inflammatory biomarker. Researchers found associations between elevated ferritin levels and increased mortality, suggesting optimal ferritin levels could improve health outcomes.
This study examined the potential of salivary glucose as a non-invasive biomarker for diagnosing type 2 diabetes. Researchers found a significant correlation between salivary and blood glucose levels, with salivary glucose showing 88.5% sensitivity. This suggests salivary glucose could be a viable alternative for diabetes screening.
Researchers analyzed fasting blood glucose levels across various diseases, finding significantly increased levels in 57 out of 64 diseases studied. The findings suggest that elevated fasting blood glucose may be a common pathophysiological characteristic of these conditions.
Researchers observed that frail elderly patients with type 2 diabetes had significantly higher fasting blood glucose and HbA1c levels. The study suggests a correlation between frailty and poor glucose control in diabetic subjects.
