How to get bun creatinine ratio?

Are you tired of not knowing what your bun creatinine ratio is? Do you feel like you’re missing out on a piece of yourself because of it? Fear not! We have compiled a comprehensive guide on how to obtain your bun creatinine ratio, whether it be for medical reasons or simply out of curiosity.

What is Bun Creatinine Ratio?

Before we delve into the nitty-gritty details of obtaining the beloved BUN Creatinine Ratio (BCR), let’s discuss what this elusive term even means. The BCR is essentially a blood test that measures two different substances in your body – blood urea nitrogen (BUN) and serum creatinine. These tests are used to evaluate kidney function.

Blood Urea Nitrogen

Blood urea nitrogen (BUN), as its name suggests, measures the amount of nitrogen in your blood that comes from the waste product urea. This waste product is created when proteins broken down by liver metabolism.

Serum Creatinine

Serum creatine levels measure another important substance in our bodies – creatine kinase, which helps create energy for our muscles. However, high levels are indicative of poor kidney function//it shows that kidneys need help to flush it away/.

Why do doctors order BUN Creatinine Ratio Tests?

Doctors can request these tests if they suspect their patients may be experiencing complications associated with poor kidney health or if someone has any unexplained muscle weakness or cramping; raising concerns on abnormal protein digestion caused due weak kidneys.

Mostly includes:

  • Poor circulation
  • Diabetes
  • Hypertension
  • Aging

What does an ideal ‘BUNCreatnine’ value look like?

An average normal range falls under:

1.Blood Urea Nitrogen | 7mg/dL–20 mg/Dl

2.Serum Creatnin Levels | 0.6mg/dL – 1.2 mg/dL

It is imperative to note values will vary depending on factors such as age or gender.

Who needs a Bun Creatinine test?

BCR tests are typically ordered for those exhibiting certain symptoms that may indicate kidney problems, illnesses like:

  • high blood pressure
  • heart disease
  • anemia
  • peripheral vascular disease

Also can be useful to monitor :

  1. Patient’s current medication affecting kidneys/ due liver metabolism

Few common medical conditions include

  Thyroid Hormone Imbalance leading towards hyperthyroidism // Graves’ Disease


  Metabolic disturbances in sugar absorption from the digestive system// Diabetes Mellitus
  1. Athletes who should know

      Whether they require intense hydrations for maintaining creatine intake.
  2. Pregnant females

     As expecting mothers undergoing BCR examination allows knowing if their existing renal condition also affect   
      their baby’s development.

Understanding and Preparing For The Test

The procedure of getting a BUN creatinine ratio test done is quite simple and straightforward, with no invasive measures required unlike other laboratory procedures.

However, there are some preparations involved prior to testing day:

  • Consult your doctor about discontinuing certain medication intakes entirely/for few days before taking this test due reasoning’s behind its effects on kidney function

Examples Include :

    Blood Diuretics | Furosemide (Lasix) , ethacrynic acid(Edecrin)


    Antibiotics | gentamicin antibiotics which put strain on yorchidney

DO NOT consume any food replacement protein drinks/supplements at least 24 hours before testing; it hugely affects serum creatinine levels leading towards misinterpretation of results during routine diagnosis!

This precautionary step saves both you and your healthcare provider time money and hassle!

Procedure of the Test

As mentioned earlier, getting such tests done is a routine blood testing process which will yield accurate results once given proper care.

The institution or doctor’s office will request that you do not eat anything six to eight hours before they take a sample of your blood. The test may seem slightly uncomfortable as doctors/staff would place a needle gauge through the bend in the elbow stretching back towards veins access.

To get optimal results it is essential you are instructed about patient position during diagnosis; Flexing/Clenching areas within forearms right before insertion helps ensure greater blood flow acquisition necessary for efficiency.

Where Can You Get A BUN Creatinine Ratio Blood Test?

BCR analyzing isn’t done on walk-in basis counters mainly due technical complications associated with lower accuracy percentages because every clinic has different equipment processes/procedures when it comes to drawing/analyzing blood samples.

It’s best to schedule appointments at preferred clinics/hospitals/laboratories beforehand to enjoy comfort and quick responsive services.

Final Thoughts: Our Advice To You!

Always stay aware by taking care !! Ensuring good kidney function/care should be top priority from diet plan modifications ,through aerobic exercises, also drug usage monitoring etc..

Take notes/actions related pills/interventions after careful consultations among qualified health professionals and always have regular checkups scheduled based on age /existing medical conditions!

Is There Anything Else I Should Know?!

Getting an insight into our own body functions is interesting/beneficial and keeps us more conscious about daily health decisions & how they affect our kidneys- one of many multifaceted organs!
