Can LabCorp Detect Frozen Urine (Quick Answer)

A urine test is a basic procedure for diagnosing the disease. In addition, urine tests can tell you what kind of disease is in your body.

Urine tests show blood pH, bilirubin, sugar, ketones, and evidence of infection and toxicity. Many times urine is kept frozen for future needs.

Now the question is can LabCrop detect frozen urine? LabCorp only detects the overdose of drugs and urine toxicity, whether frozen or non-frozen. However, it must be processed immediately after leaving the body.

Can LabCorp Detect Frozen Urine?

Urine can be frozen for future tests. However, within a few minutes of collecting the urine, it should be kept in the freezer, sealed in a plastic bag. Otherwise, the bacteria will affect the urine. This can lead to differences in urine pH and composition. As a result, if it is tested, the correct result may not be obtained.

Keeping urine frozen is a very old method. However, LabCorp will be able to detect frozen urine if it is kept properly and immediately after collecting the urine in the freezer. But keep in mind, the temperature must have to be around 24.8 degrees Fahrenheit.

Does Urine Need to be Refrigerated for Drug Testing?

Usually, the time difference between urine collection and drug test is not more than 2 hours if kept at room temperature. If urine needs to be kept for 24 hours, it can be kept in the refrigerator. However, some drug tests need to be done before putting the urine tube in the refrigerator. 

This is because urine is cultured after being kept in the refrigerator. So urine can be kept in the refrigerator for culture. However, this time should not be more than 24 hours.

Does Freezing Urine Change the pH?

Normal urine pH is between 4.5 and 7.5. That means urine can be mildly acidic. However, the urine pH depends on the storage time and temperature. The pH of urine increases with increasing temperature.

When frozen urine is reheated, the pH returns to normal. However, there is a tendency for frozen urine to deteriorate rapidly. This is because frozen urine cannot be transferred directly to any heat source to reheat it.

Can you Use a 3-days old Urine Drug Test?

You cannot use 3days old urine for a drug test if you keep the sample at room temperature. This is because the urine begins to decompose as soon as it leaves the body. Therefore, keeping it at room temperature for more than 2 hours is not recommended. Instead, the urine is sent for a drug test as soon as it leaves the body.

If urine needs to be kept in the refrigerator, it can be kept for 24 hours. However, after taking it out, it should be kept at room temperature for some time.

If the urine does not need to be tested within 24 hours, you can keep it in the freezer sealed in a plastic bag. It can store urine for up to 1 year. However, it is better to save up to 6 months. Just you have to reheat before drug testing.
