All Tests

The test measures ketone levels in your urine. Normally, your body burns glucose (sugar) for energy. If your cells don't get enough glucose, your body burns fat for energy instead. This produces a substance called ketones, which can show up in your blood and urine. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death. A ketones in urine test can prompt you to get treatment before a medical emergency occurs.

Other names: ketones urine test, ketone test, urine ketones, ketone bodies

The kidneys function as our body’s filters, cleaning the blood of waste and impurities. They also release hormones that regulate blood pressure, control production of red blood cells, and promote growth of healthy bones.

Those people who need kidney transplants have suffered from some form of kidney failure, which can be a result of diabetes, high blood pressure or a number of diseases that can be inherited. If left untreated, kidney failure can be fatal.

When skin is injured, fibrous tissue called scar tissue forms over the wound to repair and protect the injury. In some cases, scar tissue grows excessively, forming smooth, hard growths called keloids. Keloids can be much larger than the original wound. They’re most commonly found on the chest, shoulders, earlobes, and cheeks. However, keloids can affect any part of the body. Although keloids aren’t harmful to your health, they may create cosmetic concerns.

A keloid is an abnormal proliferation of scar tissue that forms at the site of cutaneous injury (eg, on the site of a surgical incision or trauma); it does not regress and grows beyond the original margins of the scar. Keloids should not be confused with hypertrophic scars, which are raised scars that do not grow beyond the boundaries of the original wound and may reduce over time. [1] See the image below.

keloids are benign dermal fibroproliferative tumors with no malignant potential. The first description of abnormal scar formation in the form of keloids was recorded in the Smith papyrus regarding surgical techniques in Egypt around 1700 BC. [2] The term keloid, meaning "crab claw," was first coined by Alibert in 1806, in an attempt to illustrate the way the lesions expand laterally from the original scar into normal tissue. [3] Since that time, physicians have attempted to characterize normal scars, hypertrophic scars, and keloids.

Keratosis pilaris (ker-uh-TOE-sis pih-LAIR-is) is a common, harmless skin condition that causes dry, rough patches and tiny bumps, usually on the upper arms, thighs, cheeks or buttocks. The bumps generally don't hurt or itch.Keratosis pilaris is often considered a variant of normal skin. It can't be cured or prevented. But you can treat it with moisturizers and prescription creams to help improve the appearance of the skin. The condition usually disappears by age 30.

When you get a kidney transplant, a healthy kidney is placed inside your body to do the work your own kidneys can no longer do.  On the plus side, there are fewer limits on what you can eat and drink, but you should follow a heart-healthy diet. Your health and energy should improve.  In fact, a successful kidney transplant may allow you to live the kind of life you were living before you got kidney disease. Studies show that people with kidney transplants live longer than those who remain on dialysis.On the minus side, there are the risks of surgery.  You will also need to take anti-rejection medicines for as long as your new kidney is working, which can have side effects.  You will have a higher risk for infections and certain types of cancer.Although most transplants are successful and last for many years, how long they last can vary from one person to the next. Many people will need more than one kidney transplant during a lifetime.

When you know the symptoms of chronic kidney disease (CKD), you can get treatment and feel your best. CKD symptoms can be subtle. Some people don’t have any symptoms — or don’t think they do. If you have one or more of the 15 symptoms below, or worry about kidney problems, see a doctor for blood and urine tests. Many of the symptoms on this list can be caused by other health problems. The only way to know the cause of YOUR symptoms is to see your doctor.

Our bodies produce several kinds of wastes, including sweat, carbon dioxide gas, feces (stool or poop), and urine (pee). These wastes leave the body in different ways. Sweat is released through pores in the skin. Water vapor and carbon dioxide are exhaled from the lungs. And undigested food materials are formed into feces in the intestines and excreted from the body as solid waste in bowel movements.

Urine, which is produced by the kidneys, contains the byproducts of metabolism — salts, toxins, and water — that end up in the blood. The kidneys and urinary tract (which includes the kidneys, ureters, bladder, and urethra) filter and eliminate these waste substances from our blood. Without the kidneys, waste products and toxins would soon build up in the blood to dangerous levels.

Knee pain is a common complaint that affects people of all ages. Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. Medical conditions including arthritis, gout and infections also can cause knee pain. Many types of minor knee pain respond well to self-care measures. Physical therapy and knee braces also can help relieve knee pain. In some cases, however, your knee may require surgical repair.

Our knees are constantly at work whether we are walking, standing, or sitting. The consistent stress makes them vulnerable to injury and pain. However, there are some time-tested home remedies for knee pain to prevent the pain from worsening.

Kawasaki disease is a rare childhood illness that affects the blood vessels. The symptoms can be severe for several days and can look scary to parents. But then most children return to normal activities.

Kawasaki disease can harm the coronary arteries, which carry blood to the heart muscle. Most children who are treated recover from the disease without long-term problems. Your doctor will watch your child for heart problems for a few weeks to a few months after treatment.

The disease is most common in children ages 1 to 2 years and is less common in children older than age 8. It does not spread from child to child (is not contagious).

Keratitis is the medical term for inflammation of the cornea. The cornea is the dome-shaped window in the front of the eye. When looking at a person's eye, one can see the iris and pupil through the normally clear cornea. The cornea bends light rays as a result of its curved shape and accounts for approximately two-thirds of the eye's total optical power, with the lens of the eye contributing the remaining one-third. Only the very thin tear film lies between the front of the cornea and our environment.

The cornea is about 0.5 millimeter thick. The back of the cornea is bathed in the aqueous fluid that fills the anterior chamber of the eye. The cornea has a diameter of about 13 millimeters (½ inch) and, together with the sclera (the white part of the eye) forms the entire outer coat of the eye.

We see through the cornea, which is the clear outer lens or "windshield" of the eye. Normally, the cornea has a dome shape, like a ball. Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape and the cornea bulges outward like a cone. This condition is called keratoconus.

Kidney cancer -- also called renal cancer -- is a disease in which kidney cells become malignant (cancerous) and grow out of control, forming a tumor. Almost all kidney cancers first appear in the lining of tiny tubes (tubules) in the kidney. This type of kidney cancer is called renal cell carcinoma. The good news is that most of kidney cancers are found before they spread (metastasize) to distant organs. And cancers caught early are easier to treat successfully. However, these tumors can grow to be quite large before they are detected.

The kidneys are two bean-shaped organs, each about the size of a fist. They lie in your lower abdomen on each side of your spine. Their main job is to clean your blood, removing waste products and making urine.

A simple kidney cyst is a round pouch of smooth, thin-walled tissue or a closed pocket that is usually filled with fluid. One or more may form within the kidneys. Simple cysts are the most common type of kidney cyst. They are not the same thing as polycystic kidney disease, which is a progressive disease that can lead to kidney failure. Simple kidney cysts most often do not cause harm.

Kleptomania (klep-toe-MAY-nee-uh) is the recurrent inability to resist urges to steal items that you generally don't really need and that usually have little value. Kleptomania is a rare but serious mental health disorder that can cause much emotional pain to you and your loved ones if not treated.

Kleptomania is a type of impulse control disorder — a disorder that's characterized by problems with emotional or behavioral self-control. If you have an impulse control disorder, you have difficulty resisting the temptation or drive to perform an act that's excessive or harmful to you or someone else.

Many people with kleptomania live lives of secret shame because they're afraid to seek mental health treatment. Although there's no cure for kleptomania, treatment with medication or talk therapy (psychotherapy) may help to end the cycle of compulsive stealing.

A bursa is a closed, fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. Bursae is plural for bursa. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees. When a bursa becomes inflamed, the condition is known as bursitis. Most commonly, bursitis is caused by local soft-tissue trauma or strain injury, and there is no infection (aseptic bursitis). On rare occasions, particularly when the immune system is suppressed, the bursa can become infected with bacteria. This condition is called septic bursitis.

Krabbe disease, also known as globoid cell leukodystrophy or galactosylceramide lipidosis, is an autosomal-recessive sphingolipidosis caused by deficient activity of the lysosomal hydrolase galactosylceramide beta-galactosidase (GALC). GALC degrades galactosylceramide, a major component of myelin, and other terminal beta-galactose–containing sphingolipids, including psychosine (galactosylsphingosine). Increased psychosine levels are believed to lead to widespread destruction of oligodendroglia in the CNS and to subsequent demyelination. [1, 2, 3]

Krabbe originally described a condition with infantile onset that was characterized by spasticity and a rapidly progressive neurologic degeneration leading to death. Since the original description, numerous cases have been documented that show a wide distribution in age of onset.

The spine has a series of normal curves when viewed from the side. These curves help to better absorb the loads applied to the spine from the weight of the body. The cervical spine (neck) and lumbar spine (lower back) are have a normal inward curvature that is medically referred to as lordosisor "lordotic" curvature by which the spine is bent backward. The thoracic spine (upper back) has a normal outward curvature that is medically referred to as kyphosis or the "kyphotic" curve by which the spine is bent forward. In this discussion, the term kyphosis will be used to discuss abnormal kyphosis.

The spine is normally straight when looking from the front. An abnormal curve when viewed from the front is called scoliosis. Scoliosis can occur from bony abnormalities of the spine at birth, growth abnormalities especially with adolescence, degenerative spinal changes in adulthood, or abnormal twisting of the vertebrae because of muscle spasm after an injury.

The normal curves of the spine allow the head to be balanced directly over the pelvis. If one or more of these curves is either too great or too small, the head may not be properly balanced over the pelvis. This can lead to back pain, stiffness, and an altered gait or walking pattern.
