Detect Blood in Urine Step 1

Step 1. Evaluate the color of your urine

The blood will often give it a red, pink or brown color (similar to the shade of Coca-Cola). After you have urinated, take a step back to examine the color of your urine before flushing the toilet for abnormal coloring.

  • It should be transparent or have a slight yellow tint. It should look like fresh squeezed lemon juice.
  • If it is dark yellow in color, it could indicate that you are dehydrated. Increase your water intake to two liters per day for healthier colored urine.
  • Dark or orange urine can also be a sign of a liver problem, especially if your stools are light in color or if you have yellow skin. See your doctor immediately if you have noticed these symptoms.

Step 2. Assess the symptoms

Blood in the urine can often be a symptom of a problem with your bladder, urinary system, or kidneys.

  • Have you had any pain or irritation recently when going to the bathroom? Did you have trouble controlling your urination or do you feel burning when you urinate? If so, it could be a sign of a UTI.
  • Have you had kidney pain? You will usually feel it in the back. Your kidneys are located under the ribs on either side of the spine, not in the drop of the back or above the buttocks as is often believed. If you have back pain, it could be the result of inflammation or irritation of the kidneys.
  • Are you a long distance runner? It is possible to find blood in the urine after vigorous exercise, especially in marathon runners. In this case, the presence of blood is usually harmless, but you should still see a doctor.
  • Are you on your period? It is possible to see blood in the urine during menstruation. Even though it is safe to do so, you should still see a doctor if symptoms persist after your period has ended.

Step 3. Contact your doctor

If you notice any problem you should contact your doctor. Even if there is no cause for concern, it is still a symptom that should not be ignored that should be examined by a professional doctor.

Start by making an appointment with your GP. He will know your medical history and he can give you tests to find the source of the problem. They may also recommend a specialist (eg urologist) if you need more specific treatment in a certain area of ​​the body or if you have a particular disease, such as kidney disease

Step 1. Bring him sample

He'll probably want to test your urine, although he'll also check for other problems like kidney pain or bladder pain. The sample will allow him to find the underlying cause of the onset of this symptom.

  • He's going to ask for a urinalysis. If the analysis reveals the presence of E. coli, you probably have a bladder infection also called cystitis. It could also reveal the presence of bacteria in the gastrointestinal system that originate from the anus. In this case, you have rather a urethritis or urethral infection. The sample could also reveal the presence of cancer cells.
  • If you find a large amount of protein in it, it could be a symptom that indicates that you have kidney disease.

Step 2. Have a blood test

Your doctor may also decide to give you a blood test in addition to the urine test. This will usually be done in his office, but he could also send you to a laboratory specializing in this type of analysis. The sample will then be analyzed for different disorders.

Your doctor may order a blood test to determine the presence of creatinine, a waste product that is normally filtered by the kidneys and taken from the blood. If you have a high level of it in your body, it could indicate a problem with your kidneys

Step 3. Have a biopsy

If the blood and urine sample indicates a bigger problem with the kidneys, the doctor may want to take a biopsy. He will take a small piece of tissue from the kidneys to examine it under a microscope. It is a very widespread procedure.

  • You will be given local anesthesia and the doctor will use an ultrasound to guide the needle for the biopsy into the kidney.
  • Once the tissue has been removed, it will be examined by a pathologist in a laboratory. You should get a call from your doctor within a week with the results and possible treatment if so.

Step 4. Pass further tests

Your doctor will likely prepare a diagnosis for you after testing your urine and blood. If he doesn't have one, he may want you to have other tests like a cystoscopy or an imaging test.

  • Cystoscopy is a more invasive procedure than a biopsy. A tubular instrument is inserted into the bladder through the urethra to look for abnormal lumps or tumors in the area.
  • A urinary system X-ray could also reveal lumps or tumors that could be blocking and causing blood in your urine. The doctor will usually order this kind of test if the cause of the hematuria is still not clear after the first few tests.

Step 5. Complete the treatment

Treatment for hematuria will vary depending on the underlying cause. If you have a urinary tract infection your doctor will prescribe antibiotics to take, usually once or twice a day in tablet form. If you have kidney stones, you may be given shock wave therapy.

He may not find any serious cause that can explain the presence of hematuria. In this case, he will not prescribe any treatment for you and you will have to watch for the return of this disorder

Detect Blood in Urine Step 9

Step 1. Learn about the causes

Hematuria can be caused by many conditions, some harmless, others more serious. In milder cases, it can be caused by periods or excessive exercise (especially if you are dehydrated). Some of the more serious causes are:

  • urinary tract infection
  • blood clots or bleeding problems like hemophilia
  • kidney stones
  • kidney disease or diabetes
  • inflammation of the prostate
  • trauma or injury to a kidney
  • kidney, bladder or prostate cancer

Step 2. Beware of invisible symptoms

There are actually two types of hematuria: macroscopic and microscopic. With gross hematuria, you may be able to see blood with the naked eye because of the pink, red, or brown tint in the urine. However, if you have microscopic hematuria, you will not be able to detect it by simply observing your urination.

If anyone in your family has had kidney, bladder, or prostate cancer in the past, you should have a doctor test your urine at your annual check-up, especially if you are over 40. Microscopic hematuria can be a symptom of a more serious disease of the urinary system that can only be detected during a test

Step 3. Prevent the return of hematuria

Although the specific steps for prevention will vary depending on what is causing blood in your urine, there are usually steps you can take to prevent it.

  • If it is caused by a UTI, you need to drink plenty of fluids (about two liters per day) to stay hydrated. If you are a woman, you should make sure to wipe yourself from front to back when using the toilet to prevent bacteria from spreading from your anus into your urethra.
  • If it is caused by kidney stones, drink plenty of water and avoid foods high in salt.
  • If it is caused by bladder or kidney cancer, you should drink plenty of fluids, eat a healthy diet with lean meats and vegetables, and quit smoking. Light or moderate exercise can also prevent this symptom from coming back.
