What happens during a microalbumin creatinine ratio?
For a microalbumin creatinine ratio you will be asked to provide either a 24-hour urine sample or a random urine sample.
For a 24-hour urine sample, you will need to collect all urine passed in a 24-hour period. Your health care provider or a laboratory professional will give you a container to collect your urine and instructions on how to collect and store your samples. A 24-hour urine sample test usually includes the following steps:
Empty your bladder in the morning and flush that urine down. Do not collect this urine. Record the time.
For the next 24 hours, save all your urine passed in the container provided.
Store your urine container in the refrigerator or a cooler with ice.
Return the sample container to your health provider's office or the laboratory as instructed.
For a random urine sample, you will receive a container in which to collect the urine and special instructions to ensure the sample is sterile. These instructions are often referred to as the "clean catch method." The clean catch method includes the following steps:
Wash your hands.
Clean your genital area with a cleansing pad. Men should wipe the tip of their penis. Women should open their labia and clean from front to back.
Start to urinate into the toilet.
Move the collection container under your urine stream.
Collect at least an ounce or two of urine into the container, which should have markings to indicate the amount.
Finish urinating into the toilet.
Return the sample container as instructed by your health care provider.
