Why Creatinine Serum Test is so important, and how to test it?

What is creatinine and creatinine test?

Creatinine is a waste product that the body’s muscles naturally make during normal wear and tear. Creatine phosphate is a high-energy substance found in your muscles. The kidneys remove creatine phosphate from the blood, continuously created as a byproduct. We all have creatinine in our blood. Increased blood (or serum) creatinine occurs when the creatinine clearance gets reduced. A creatinine test helps determine whether you have kidney impairment and if your blood creatinine level has increased.

What is the normal creatinine level?

Creatinine has a normal range depending on age, race, gender, and body size.

  • For adult men, the normal creatinine range is 0.74 to 1.35 mg/dL.
  • For adult females, the normal creatinine range is 0.59 to 1.04 mg/dL.
  • Older adults may have lower blood creatinine levels than the average population. In contrast, muscular young or middle-aged adults may have higher levels. Due to a gradual decrease in weight, individuals with chronic illnesses and malnutrition may have lower creatinine levels.

Therefore, A creatinine level of more prominent than 1.2 for ladies and more noteworthy than 1.4 for men might be an early sign that the kidneys are not working as expected. As kidney sickness advances, the degree of creatinine in the blood rises.

Why is a creatinine serum test required?

When you see signs of kidney illness or want to check your kidney health, a creatinine serum test is needed to check your creatinine levels.

The symptoms listed below may point to kidney-related problems:

  • Fatigue cannot be attributed to another factor.
  • An eyelid ring of puffiness.
  • Swelling in your ankles or feet.
  • Regular and uncomfortable urinating.
  • Bloody or foamy urine.

You are more likely to get kidney disease if these conditions are there:

  • A history of renal illness in the family.
  • Diabetes type 1 or type 2.
  • Excessive blood pressure.

How do you get prepared for a creatinine test?

The creatinine serum test usually doesn’t require any planning. Your doctor can advise specific preparations, depending on the test, to guarantee proper results. For example, you might be instructed to abstain from eating cooked meat for 24 hours before the test. You can be advised to wait two days before receiving a creatinine test before engaging in vigorous activity. Your levels of creatinine may rise if you eat meat and exercise hard.

It’s essential to stay hydrated and consume plenty of fluids throughout the 24-hour testing. This condition is for people who have a creatinine urine test. Use the container your doctor gives you and follow their instructions while collecting your urine for 24 hours.


Your creatinine levels may rise as a result of some medications. Any drug or over-the-counter medications you take should be informed to your doctor. Medications like cimetidine, chemotherapeutic agents, and cephalosporin antibiotics can affect the outcomes of tests. This could be taken into account by your doctor when analyzing the outcomes of your blood tests.

Therefore, as a consequence, Creatinine is a side-effect that the body’s muscles normally make during typical mileage. Creatine phosphate is a high-energy substance tracked down in your muscles. The kidneys eliminate creatine phosphate from the blood, persistently made as a result. We as a whole have creatinine in our blood. Expanded blood (or serum) creatinine happens when the creatinine leeway gets decreased.

A creatinine test decides if you have kidney debilitation and if your blood creatinine level has expanded. Your kidneys are important organs that remove harmful body waste and help you stay healthy. Keep yourself hydrated and include fresh, green vegetables in your diet. In addition to getting your serum creatinine and kidney function evaluated occasionally, you must follow these suggestions. Exercise also helps in keeping your kidneys healthy and operating properly.
