If properly sealed and stored, urine samples are good for testing up to 24 hours after the sample given. The urine sample should be in a sterile container within a sealed plastic bag and stored in a refrigerator.
Collected urine samples can be contaminated by bacteria from the genital area, skin, or external environment, which can affect the accuracy of test results. It is important to follow proper collection and handling procedures to minimize the risk of contamination.
Processing urine samples within one hour is crucial to prevent degradation of analytes, which can lead to inaccurate test results. Delayed processing can result in changes in pH, increased bacterial growth, and the breakdown of substances like glucose and proteins. Additionally, timely analysis helps maintain the stability of certain biomarkers, ensuring that diagnostic conclusions are reliable and relevant. Prompt handling also minimizes contamination risks and preserves the integrity of the sample for further testing if needed.

Controls in urine testing are used to ensure the accuracy and reliability of the test results. They are samples with known concentrations of the analyte being tested for, used to validate the test procedure and equipment. Control samples are run alongside patient samples to verify that the test is working correctly and to detect any errors in the testing process.
In the bladder. Or if that's the question: Urine samples should be stored in the fridge if they can't get analysed immediatly.
Chlamydia is typically detected through urine or swab samples, not blood samples. Blood tests are not commonly used for diagnosing chlamydia.
