Why should we not squeeze the finger for taking the blood?

After pricking your finger with the lancet, you should need to apply only slight pressure to release blood flow. If you need to apply a lot of pressure to produce a sample, that finger may not be the best testing site for you. Squeezing or milking the finger can contaminate the sample and lead to inaccurate results.

When using a blood glucose monitor, it is important to get the most accurate readings possible to gain meaningful insight into your health and detect patterns in your blood glucose levels. The FDA mandates that results from self-monitoring blood glucose systems be within 15% of lab results 95% of the time. But accuracy doesn’t depend just on the capabilities of the monitor; it also depends on how the user performs a test. This includes where you choose to collect your blood sample from. So which finger is best to test blood sugar? It depends. Read on to find out more.

Why Finger-Prick Testing?

Finger-prick tests are typically the best way to monitor your blood glucose levels. Plentiful capillaries or small blood vessels in the fingertips make them bleed well and reliably produce samples for testing. Blood samples taken from a fingertip will show blood sugar level changes faster than those taken from other areas of the body due to the increased blood flow in the fingertips. After a carb-heavy meal, for example, a finger-prick test will show blood sugar increases much sooner than a test from your forearm. However, not all finger-prick tests will produce the same results, even if taken at the same time. This is, in part, because samples will vary slightly due to the differing amounts of cells and interstitial fluid (the fluid between the cells) they contain. This means that if you do multiple tests back-to-back using the same finger, the results can be slightly different. To support accurate finger-prick testing, always wash your hands with soap and water before testing. This removes any residue that could affect results and warms the finger to make getting a blood sample easier. While slight variations like those mentioned above are natural, residue from food or even incompletely dried hands can create significant inaccuracy in your test results.

Which Finger Is Best to Test Blood Sugar?

People living with diabetes rely on frequent blood glucose testing to properly monitor and manage their health. For some, that means obtaining blood samples up to 10 times a day. So which finger is best to test blood sugar if you want the most accurate results in the easiest way possible?

The answer: it depends. Some people use a different finger each time to prevent soreness and callusing. Others find that a particular finger works best and uses that finger repeatedly. They may prefer to test on a callused finger, as calluses can decrease sensitivity.

Why can't diabetics take baths?

People with diabetes often have dry feet or nerve damage that results from diabetic neuropathy. When wounds such as blisters develop, they can take a long time to heal, and they can get worse quickly. Prolonged soaking can also open small cracks that may be present in the skin, allowing germs to enter.

A common complication of diabetes is foot problems. Many people use Epsom salt as a soothing remedy for their feet, but should a person with diabetes use it? People with diabetes can have high levels of blood sugar. This can lead to nerve damage and insufficient blood flow, which make it harder for wounds to heal. This in turn can result in serious foot problems, including, in some cases, a need for amputation. If a person with diabetes soaks their feet, it can lead to severe complications. This article looks at the relationship between diabetes and Epsom salt and whether or not Epsom salt — or magnesium sulfate — is a suitable foot remedy. It also provides foot health tips for people with diabetes. Epsom salt and diabetes Share on Pinterest Gabriel Mello/Getty Images Epsom salt is a mineral compound with many different uses, but people with diabetes should avoid using it. No form of foot soak is appropriate for individuals with diabetes. People use Epsom salt as a home remedy for various health issues. Its proponents claim that it provides a range of health and beauty benefits, such as: soothing muscle aches and pain

providing relief from sunburn and poison ivy itches
