Important Update Regarding Laboratory Services!
KSOSN is pleased to announce the expansion of our laboratory services. Beginning August 24, 2026, KSOSN will be providing laboratory processing services through our own in-house laboratory. This enhancement allows us to further integrate laboratory services with the care you already receive from our nephrology team.
What Does This Mean for You?
For most patients, the process will remain the same.
No appointment is required for specimen collection.
Patients may continue to stop by during normal office hours for blood draws and other provider-ordered laboratory testing.
Your specimen will continue to be collected by our clinical team.
Your provider will continue to receive and review your results as part of your ongoing care.
Insurance Requirements
Some insurance plans require laboratory testing to be performed through a specific laboratory provider, such as LabCorp or Quest Diagnostics. If your insurance requires you to use one of these laboratories, you will need to use their designated facility. If you are unsure where your laboratory testing should be completed, our team will be happy to assist you.
What You May Notice
You may begin seeing Kidney Specialists of Southern Nevada listed as the laboratory provider on laboratory reports, insurance explanations of benefits, or billing statements.
Benefits of Our In-House Laboratory
· Convenient walk-in specimen collection
· Enhanced coordination between your care team and laboratory services
· Improved continuity of care
· Local laboratory support through KSOSN
· Improved access to laboratory results for your providers
· Potential for faster turnaround times on certain tests
