What is Creatinine Test?
A creatinine blood test measures the amount of creatinine in the bloodstream of a human body. The muscles in our body contain creatine which helps in recycling adenosine triphosphate. Adenosine triphosphate is the energy currency for our cells and needs to be recycled at all costs. When creatine breaks down, it produces a waste substance. The waste substance is known as creatinine and needs to be eliminated from the body. Sometimes, creatinine is not removed from the body at frequent intervals, which can cause future complications. Since creatinine is a waste material, it should be discharged and not present in the bloodstream.
Kidneys in the human body consist of more than a million nephrons. These nephrons are responsible for filtering blood. With the help of a tiny cluster of glomeruli, nephrons filter the blood in the human body. Excess water and other impurities are discharged from the body using nephrons. Ideally, kidneys should remove creatinine from the body as it is a waste substance. When the kidneys fail or become damaged, they do not discharge creatinine at frequent intervals. Creatinine is not collected in the bladder and is not removed during urination. As a result, the creatinine levels in the bloodstream rise. It is vital to measure kidney functions at frequent intervals. With a creatinine blood test, the functioning of the kidneys can be measured. Read on to know more about a creatinine blood test and its usefulness.
Frequently asked questions
The creatinine blood test measures the amount of creatinine in the patient's bloodstream. If the creatinine levels are high in the body, it indicates a kidney ailment. The amount of creatinine in the body is measured in milligrams per decilitre of blood (mg/dL). Knowing the creatinine levels in the body can help predict several diseases. The creatinine levels should be low in the bloodstream as the kidneys discharge them.
A creatinine blood test is needed to monitor the creatinine levels in the blood. People suffering from kidney diseases have to take the creatinine blood test to monitor their treatments. If the creatinine levels in the body decrease, the treatment is going in the right direction. Creatinine test results also give an indication of several diseases and conditions in the body.
Any problems with the kidney can lead to a creatinine blood test. Symptoms of several diseases might also call for a creatinine blood test. Some symptoms that call for a creatinine blood test are as follows:
- Excessive fatigue
- Excessive swelling in the ankles, wrists, or face
- Lower backache
- Changes in the normal urine frequency
- High BP
- Frequent vomiting
- Diabetic symptoms
Creatinine levels in milligrams per decilitre of blood are showcased via a creatinine blood test. For men, the normal creatinine levels in the body range from 0.9 to 1.3 mg/dL. For women, the range is between 0.6 to 1.1 mg/dL. Usually, muscular people have higher levels of creatinine in their bodies.
A healthy individual can take a creatinine blood test once a year as a precautionary measure. However, kidney failure patients might have to take a creatinine blood test more often. People having a family history of kidney ailments should take a creatinine blood test every quarter.
A home sample collection facility is available for a creatinine blood test. However, you may have to pay more than usual for home sample collection. For the same reason, it is better to walk up to a nearby diagnostic centre and take a creatinine blood test.
