Low insulin levels occur when the beta cells of the pancreas do not produce enough insulin, according to the American Association for Clinical Chemistry. This can occur in diabetes, hypopituitarism or pancreatitis.Know More
Insulin is a hormone produced and stored in the beta cells of the pancreas, explains the American Association for Clinical Chemistry. Insulin helps to transport glucose into cells. If there is too little insulin or there is resistance to insulin, the cells starve. Glucose is unable to enter the cells and remains in the blood, resulting in high blood glucose levels. High insulin levels occur in insulin resistance, obesity, acromegaly, Cushing syndrome and insulinoma.
Doctors should evaluate insulin levels in the context of blood glucose levels, states the American Association for Clinical Chemistry. Low levels of insulin with high levels of glucose in the blood indicate inability of the beta cells to produce insulin in diabetes or pancreatitis. High levels of insulin with high or normal levels of glucose indicate insulin resistance. High or normal levels of insulin with low levels of glucose indicate hypoglycemia due to excess insulin.
Doctors are likely to order insulin testing in people with low glucose levels. They also order the test for people who exhibit symptoms such as fainting, profuse sweating, palpitations, blurred vision, confusion and unusual hunger.Learn more about Medical Ranges & Levels
Sudden or chronic bleeding, such as gastrointestinal and heavy menstrual bleeding, may cause a low red blood cell or RBC count, according to the American Association for Clinical Chemistry. Iron, vitamin B12 and folate deficiencies may also decrease red blood cell count.Full Answer >
A raised MCV, or mean corpuscular volume, means the red blood cells are larger than they should be, explains the American Association for Clinical Chemistry. Counting red blood cells and measuring their size helps diagnose different types of anemia.Full Answer >
Anion gap is the difference between the measured and unmeasured ions in plasma, explains the American Association for Clinical Chemistry. The test helps diagnose problems with the acid-base balance in the body.Full Answer >
Infections and inflammation usually cause high white blood cell counts, according to the American Association for Clinical Chemistry. The elevated count can be also be attributed to allergic responses, severe stress and pregnancy. Medications such as corticosteroids and epinephrine boost white blood cells as well, according to the Mayo Clinic.Full Answer >
