When the creatine found in our muscles breaks down, it creates a waste product called creatinine. The creatinine test tells us the measure the amount of creatinine in the blood. By looking at the amount of creatinine in the blood, the doctor can see whether your kidneys are working correctly. The kidney might not function properly for many reasons. It can be an infection or trauma or anything else. Corona infection also sometimes leads to kidney damage. Therefore, keeping yourself safe from the corona is of utmost importance during the pandemic. The government has made it mandatory for everyone to take an antigen fit to fly test who is planning to go abroad. This is one of the measures that the govt has taken to prevent the spread of coronavirus. 

Each kidney contains millions of blood-cleansing plants called nephrons. Nephrons clean the blood from a group of very tiny blood vessels called glomeruli. All these together clean the waste products, excess water, and other impurities present in the blood. Creatinine is one of those impurities that the kidney keeps on removing from the body. For this reason, doctors look at kidney function through a creatinine test. If the amount of creatinine in the blood is excessive, it simply means that your kidney is not working correctly. Creatinine blood tests are done along with several other governments approved lab tests, such as the blood urea nitrogen (BUN) test, the basic metabolic panel (BMP), and the comprehensive metabolic panel (CMP). Such tests are done along with routine tests to check for other problems in the body and kidney function.

Why is the creatinine test done?

Along with telling the amount of creatinine in the blood, the cerium creatinine test also tells how the kidney works. It also tells us how much damage has been done. It has been found that the higher levels of creatinine the blood has, the more damaged the kidneys are. Anyone who has damaged kidneys should consult a doctor before planning a long journey abroad. Your doctor can recommend you some important tests including creatinine to know if you are good to fly. You will also require to take an antigen fit to fly test nowadays because of the pandemic. But, before you go to the doctor, here are some symptoms that can help you understand if your kidneys are damaged. The symptoms are as follows. 

  • Insomnia
  • loss of appetite
  • swelling of the hands, stomach, or mouth
  • back pain around the kidney
  • more or less urine
  • high blood pressure
  • Vomit
  • Nausea

Many people have travelled to the UK and are in mandatory quarantine of 10 days and are required to take the day 2 & 8 tests. In such a condition it is difficult to order a test online for creatinine. Therefore, knowing the above-mentioned symptoms can help you judge the level of the problem.

The following can also cause kidney problems:

  • glomerulonephritis, which is inflammation of the glomeruli due to damage. 
  • Pyelonephritis is a bacterial infection of the kidney
  • Prostate diseases such as an enlarged prostate
  • Blockage in the urinary tract, which a kidney stone can cause
  • decreased blood flow to the kidneys, which can result in heart failure, diabetes, or dehydration
  • destruction of kidney cells
  • Streptococcal infection
  • Coronavirus infection can also lead to kidney damage in some cases.

We advise you not to travel if you have any one of the above-mentioned conditions. You may clear your antigen fit to fly test but that doesn’t mean that you won’t be at a higher risk of kidney failure. It is better to get the underlying reason for kidney malfunction cured before you go out on a trip.

The doctor may recommend this test for the following health conditions:

  • If you have type 1 or 2 diabetes, your doctor may recommend a yearly creatinine test.
  • Suffer from any kidney disease.
  • Any conditions that affect the kidneys, such as high blood pressure, or diabetes.
  • Amino-glycoside antibiotics such as gentamicin can also cause kidney failure in some people. Your doctor may recommend this test to see if your kidneys are healthy, even if you are taking these medicines.
  • A covid test to know if the damage is caused due to corona infection. This might be done if the doctor thinks that you are asymptomatic. You can also get yourself tested for corona by ordering a corona kit from any of the government approved providers.

Preparation for a Creatinine Test?

The serum creatinine blood test is similar to a routine blood test. It does not require any special preparation before the test. Depending on your condition, your health expert may give you specific guidelines. In many cases, the doctor may also test the amount of creatinine in your urine. For this, the physician may ask to keep the number of urine in 24 hours in different special boxes. Unlike the day 2 &8 swab tests that you can do yourself, creatinine urine tests take more time and should be done under proper supervision. 

What do my test results say?

You can measure creatinine blood test results in milligrams per deciliter or micromoles per litre. Its normal range should be 0.84 to 1.21 mg per deciliter (74.3 to 107 micromoles per litre). However, the results of this test depend on the lab, the age of the patient, and the body of women and men. The level of creatinine in the blood rises due to overweight muscles. Therefore, more creatinine is present in men than in women. In general, indeed, high levels of creatinine in the blood are directly related to abnormal kidney behaviour. If you have dehydration, anaemia, consume more meat, or are taking any medicine, the amount of creatinine may increase for some time. Follow a healthy lifestyle to keep your kidneys safe.
