Blood Glucose Test Normal Range: Fasting, Random, and After-Meal Levels
A blood glucose test measures how much glucose, or sugar, is in your blood at the moment the sample is taken. Glucose rises and...
Blood Ketones Test: High Ketones, Normal Range, Diabetic Ketoacidosis, and Results
A blood ketones test measures ketones in the bloodstream, usually beta-hydroxybutyrate, the main ketone that rises during diabetic ketoacidosis. Ketones can increase for harmless...
Comprehensive Metabolic Panel (CMP) Test: Markers, Normal Ranges, Liver, Kidney, and Results
A comprehensive metabolic panel, often called a CMP, is a common blood test that checks 14 measurements from one blood sample. It gives a...
C-Peptide and Insulin: Interpreting Diabetes Type and Insulin Production
C-peptide and insulin are closely related blood tests, but they answer different questions. Insulin shows how much insulin is circulating in the blood at...
C-Peptide Blood Test Normal Range: Reference Values and Meaning
A C-peptide blood test measures how much insulin your pancreas is making. It is most often used when diabetes type is unclear, when insulin...
Estimated Average Glucose (eAG) Test: A1c Conversion, Normal Range, Diabetes Monitoring, and Meaning
Estimated average glucose, or eAG, turns an A1c percentage into the same glucose units used on many lab reports, glucose meters, and diabetes apps....
Fasting Blood Glucose Test: Normal Range, Prediabetes, Diabetes Diagnosis, and Results
A fasting blood glucose test measures how much glucose is in your blood after you have not eaten for several hours, usually overnight. It...
Fasting Glucose and Fasting Insulin: Interpreting Insulin Resistance
Fasting glucose and fasting insulin look at the same metabolic system from different angles. Glucose shows how much sugar is in the blood after...
Fasting Insulin Test: High Insulin, Normal Range, Insulin Resistance, and Results
Fasting insulin is a blinsulin your pancreas is releasing after you have gone several hours without food. It is most often used to look...
Fructosamine Blood Test: Normal Range, Diabetes Monitoring, Short-Term Glucose Control, and Results
The fructosamine blood test measures how much glucose has attached to proteins in the blood, mainly albumin. Because these proteins turn over faster than...
Fructosamine vs A1c: Short-Term vs Long-Term Blood Sugar Monitoring
Fructosamine and A1c both estimate average blood sugar, but they look at different windows of time. A1c reflects glucose exposure over roughly the past...
Glycated Albumin Test: Normal Range, Diabetes Monitoring, Blood Sugar Control, and Results
A glycated albumin test measures how much glucose has attached to albumin, the main protein in the blood. Because albumin turns over faster than...
Glycated Albumin vs Fructosamine: Difference, Diabetes Monitoring, and Meaning
Glycated albumin and fructosamine are blood tests that estimate recent blood sugar control without relying on red blood cells. They are most often discussed...
Hemoglobin A1c (HbA1c) Test: Normal Range, Prediabetes, Diabetes Diagnosis, and Results
The hemoglobin A1c test shows how much glucose has attached to hemoglobin inside red blood cells. Because red blood cells circulate for about 3...
High Anion Gap Blood Test: Causes, Metabolic Acidosis, Ketoacidosis, and Meaning
A high anion gap blood test result means there are more unmeasured acids in the blood than expected. The anion gap is not usually...
High Blood Glucose Test Result: Causes, Hyperglycemia, Diabetes, and Meaning
A high blood glucose test result means there is more glucose, or sugar, in the blood than expected for the timing of the test....
High C-Peptide Blood Test: Causes, Insulin Resistance, Diabetes Type, and Meaning
A high C-peptide blood test usually means your pancreas is releasing a higher-than-expected amount of insulin. C-peptide rises when the body makes its own...
High Glucose and High Ketones: Diabetic Ketoacidosis Risk Pattern
High glucose and high ketones together can signal diabetic ketoacidosis, often shortened to DKA. This is a dangerous diabetes emergency where the body does...
High Insulin Blood Test: Causes, Insulin Resistance, Weight Gain, and Meaning
A high insulin blood test usually means the pancreas is making more insulin than expected for the situation. Most often, this happens because the...
High Random Blood Glucose Test: Causes, Diabetes Screening, Hyperglycemia, and Meaning
A high random blood glucose test means your blood sugar was above the expected range at the moment the sample was taken, regardless of...
