Can Lantus insulin cause serious lows? It can. Lantus (insulin glargine) is a long-acting basal insulin that is supposed to be released slowly and evenly throughout approximately 24 hours. The actual time it last varies in different patients. Bolus, or prandial, insulins are fast-acting insulins, and if you inject too much of them, or don't eat as much as you thought you were going to eat when you calculated the bolus dose, the result can be serious low blood sugar ( hypoglycemia ), because the insulin works quickly. People don't expect Lantus to cause hypoglycemia because it's supposed to be released slowly, a little bit at a time. However, although this is rare, Lantus can cause serious hypoglycemia if it's injected into a blood vessel. This happened to me once and several times to a good e-mail friend whose observational skills I trust. Neither of us uses bolus insulin. At least several people I don't know have reported similar episo...
Definition Insulin C-peptide is a blood test that measures the amount of C-peptide, a byproduct created when the hormone insulin is produced. Alternative Names C-peptide How the test is performed Blood is typically drawn from a vein, usually on the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood. Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding. In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may b...
Normally, there are no antibodies against insulin in your blood.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results mean
If you have IgG and IgM antibodies against insulin, your body reacts as if the insulin is foreign. This may make insulin less effective, or not effective at all.
The antibodies can also change the amount of time it takes insulin to work, putting you at risk for low blood sugar. This means that the insulin cannot move glucose from the bloodstream into the cells. As a result, increased levels of insulin are needed to have the same effect, which is called insulin resistance.
If the test shows high levels of IgE antibody against insulin, your body has developed an allergic response to the medication. This could put you at risk for skin reactions, or more severe reactions. Other medications, such as antihistamines or low-dose i...
