Taking a Renal Function Test (RFT) is generally a straightforward process. It primarily involves submitting a sample, as instructed by your healthcare provider, to a designated lab or hospital for analysis. Here's a breakdown of the procedure:
What is an RFT?
An RFT, or Renal Function Test, assesses the health and function of your kidneys. These tests measure various substances in your blood and/or urine to determine how well your kidneys are filtering waste products and maintaining overall balance in your body.
Preparation for an RFT
- Minimal Preparation: Typically, RFTs require very little preparation on your part.
- Doctor's Instructions: Your doctor or physician will specify the type of sample required (usually blood, urine, or both).
- Fasting May Be Required: Depending on the specific tests ordered, you might be asked to fast for a certain period before the test. Your doctor will provide these instructions if necessary.
- Medication List: Inform your doctor about all medications you are taking, as some can affect test results.
The RFT Procedure
- Sample Collection: Following the instructions provided by your healthcare provider, you will either:
- Have blood drawn by a phlebotomist.
- Provide a urine sample.
- In some cases, you may need to collect a urine sample over a 24-hour period.
- Sample Submission: You will then need to submit the collected sample to the designated laboratory or hospital.
What Happens After Sample Submission?
- Lab Analysis: The lab will analyze the sample to measure specific markers associated with kidney function.
- Result Interpretation: Your healthcare provider will review the results and discuss them with you.
Key Aspects of RFTs
- Simple Procedure: RFTs are generally simple and non-invasive.
- Specified Sample: The type of sample you need to submit (blood, urine, or both) will be specified by your doctor.
- Lab Assessment: Samples are sent to a lab or hospital for assessment.
In summary, according to the provided reference, the primary action required to take an RFT is to submit the type of sample your healthcare provider specifies to a designated lab or hospital for analysis.
