Question

In a urinalysis case study for uncontrolled diabetes mellitus if the glucose level is negative, would this mean an increase or decrease in change

Answer 1

Answer:

A person with diabetes may need to have a urine test if they notice blood in their urine, or to check for high blood sugar, diabetic ketoacidosis, or a urinary tract infection.

A urine test is non-invasive, and people often use them at home. However, healthcare professionals may use a urine test if they cannot access a vein for a blood test, or if a person has anxiety or a fear of needles.

The results may be less accurate than those of a blood test, but urine tests can still play an important role.

In this article, we look at types of urine tests for diabetes and how to understand the results.

Types of test

A urine test can detect various substances, including glucose, ketones, protein, bacteria, and bilirubin.

Glucose

A urine test is an noninvasive way of testing for glucose, ketones, and other substances.

Typically, glucose is not present in urine. However, when a person has diabetes, glucose can pass from the kidneys into the urine.

Other conditions, such as pregnancy and kidney disorders, can also lead to glucose in the urine.

Pregnancy: Around half of women have glucose in their urine during pregnancy, even if they do not have diabetes.

A person who has high levels of glucose in the urine during pregnancy may need monitoring for gestational diabetes.

This is a type of diabetes that occurs in some people during pregnancy. It usually resolves after delivery, but it can affect the fetus, lead to complications during labor, and may put the individual at a higher risk of developing type 2 diabetes later in life.

Glycosuria: This is a rare kidney condition in which a person does not have high blood glucose levels, but their kidneys excrete high levels of glucose into the urine. There are often no symptoms, but some people may experience thirst, urination, and other symptoms. In rare cases, dehydration or ketoacidosis can occur.

Ketones

When a person has diabetes, the glucose in their blood cannot enter the body's cells, and it remains in the blood. When this happens, the cells do not have enough glucose for energy.

As a result, the body starts to break down fat to use for energy instead. This produces toxic ketones. If ketone levels rise too far, they can cause the blood to become too acidic. In a person with diabetes, this can lead to diabetic ketoacidosis (DKA), a potentially fatal condition that needs emergency treatment.

Ketones can also enter the urine, so a doctor can use a urine test to detect DKA. People with diabetes can do a urine test at home if they start to experience the signs and symptoms of DKA.

According to the American Diabetes Association, symptoms of DKA include:

a "fruity" or acetone smell on the breath

frequent urination

thirst

dry or flushed skin

difficulty breathing

confusion

abdominal pain

nausea and vomiting

high blood sugar levels

In severe cases, a person may experience:

a loss of consciousness

a coma

Anyone who thinks they might have DKA should first check their blood sugar levels. If these are over 240 milligrams per deciliter (mg/dl), the ADA recommend testing for ketones.

If ketone levels are high, seek medical help at once to prevent further problems developing.

DKA often takes time to develop, but if a person experiences vomiting, it can quickly become severe. It can affect people with both type 1 and type 2 diabetes.

The risk of DKA is also higher when a person with diabetes has a cold or flu. During these times, they should test their ketone levels every 4–6 hours, according to the ADA.

Knowing about self-testing for both glucose and ketones can enable a person with diabetes to have more control over their condition.

Protein

A doctor may test for protein in the urine to monitor for kidney problems. This is because diabetes increases the risk of chronic kidney disease (CKD) and specifically diabetic nephropathy. An early sign of diabetic nephropathy is protein in the urine.

If a person receives an early diagnosis of kidney disease, they may be better able to control it through diet and possibly medications.

Bacteria

A doctor may use a urine test to check for a urinary tract infection (UTI).

People with diabetes have a higher risk of infections, including a UTI. Without treatment, this can lead to complications, such as a kidney infection.

The doctor will send the sample to a laboratory for culturing if a person has diabetes. If an infection is present, they may prescribe antibiotics.

Bilirubin

Sometimes a urine test can detect bilirubin, a substance which can indicate liver damage and certain other health conditions.

A study published in 2017 found a link between high levels of bilirubin in people with diabetes and kidney disease, retinopathy, and diabetic neuropathy, all common complications of diabetes.
