Urinalysis - What is it and Why use it?

Urinalysis - What is it and Why use it?

Urinalysis is a test on your urine. These tests are very cheap to produce and give a very fast result which is why Doctors, Nurses, NHS Finance Directors love them. If they can stop you going for a blood test and test you quickly in the clinic it helps the NHS.

A urine test involves checking the appearance, concentration and content of your urine. Abnormal urinalysis results may point to a disease or illness.

For example, a urinary tract infection can make urine look cloudy instead of clear. Increased levels of protein in urine can be a sign of kidney disease. Unusual urinalysis results often require more testing to uncover the source of the problem.

Depending on your situation, you may collect a urine sample at home or at your doctor's office. Your doctor will provide a container for the urine sample. You may be asked to collect the sample first thing in the morning because at that time your urine is more concentrated, and abnormal results may be more obvious.

What does Midstream mean?

It means what it says, the test strips needs to be placed into the stream of urine rather than placed into a specimen cup. This saves even more money for the NHS as there is no need for a single use cup.

When purchasing urine tests they are sold by the number of parameters that each strip can look out for. This can vary from one parameter looking at Glucose to 12 parameters looking at a range of indications. 

12 Parameters to look out for and why?

  • Leukocytes

Leukocytes in urine (leukocyturia) can be a sign of a bacterial urinary tract infection (UTI), such as a bladder or kidney infection

  • Nitrite

Nitrites in urine may be a sign of a urinary tract infection (UTI).

  • Urobilinogen

Urobilinogen is formed from the reduction of bilirubin. Bilirubin is a yellowish substance found in your liver that helps break down red blood cells. ... Too much urobilinogen in urine can indicate a liver disease such as hepatitis or cirrhosis.

  • Glucose

The normal amount of glucose in urine is 0 to 0.8 mmol/L. A higher measurement could be a sign of a health problem. Diabetes is the most common cause of elevated glucose levels. ... Renal glycosuria can cause urine glucose levels to be high even if blood glucose levels are normal.

  • pH

A neutral pH is 7.0. The higher the number, the more basic (alkaline) it is. The lower the number, the more acidic your urine is. The average urine sample tests at about 6.0.

  • Specific Gravity

To put it another way, the specific density of water would be 1.000. Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.

  • Ketone

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. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death.

  • Bilirubin

Bilirubin is a yellowish substance made during the body's normal process of breaking down red blood cells. Bilirubin is found in bile, a fluid in your liver that helps you digest food. Bilirubin in urine may be a sign of liver disease.

  • Protein

Healthy kidneys do not allow a significant amount of protein to pass through their filters. But filters damaged by kidney disease may let proteins such as albumin leak from the blood into theurine. Proteinuria can also be a result of overproduction ofproteins by the body. Kidney disease often has no early symptoms.

  • Microalbumin

urine microalbumin test is a test to detect very small levels of a blood protein (albumin) in your urine. A microalbumin test is used to detect early signs of kidney damage in people who are at risk of developing kidney disease.

  • Creatinine

Creatinine is a chemical waste product produced by muscle metabolism. When your kidneys are functioning normally, they filter creatinine and other waste products out of your blood. These waste products are removed from your body through urination. A creatinine urine test measures the amount of creatinine in your urine.

  • Blood

Common causes of blood in urine include: a bladder infection (such as cystitis) – which typically also causes a burning pain when you urinate. a kidney infection – which may also cause a high temperature and pain in the side of your tummy.
