Arkana is a learning, teaching, and innovating practice with one unifying passion: to work toward research breakthroughs that make our services unnecessary.

What is the biorepository?

A biorepository is a collection of human biologic samples for the purpose of research.  Research at Arkana focuses on a variety of kidney diseases, aiming to understand the underlying causes, as well as to develop non-invasive human biologic sample tests to monitor kidney disease.

Donation of human biologic samples from patients like you allow us to develop new diagnostic tests, find new biomarkers to monitor disease, and improve our understanding of your kidney disease.  While donating to the Arkana Biorepository may not benefit you directly, your efforts can help many patients to come!

Research Focus

Research at Arkana Laboratories has led to multiple advancements in the diagnosis and understanding of kidney diseases – but we still have a lot to learn and discover!   This is only possible with dedicated patients and enthusiastic clinicians helping us to make it happen.

What do we do with your sample donation?

Your sample will be processed in our laboratory, de-identified, and archived in the Arkana Biorepository to preserve for future research studies. All samples are de-identified, so that they can be used in research without compromising your privacy.   Your human biologic sample donation will be used to develop and improve serologic and molecular tests for the diagnosis and monitoring of kidney disease.

Development of these tests will enable us to measure antibodies and protein biomarkers in the blood, assess the effectiveness of treatment, and track activity of kidney disease over time.  This could help make more informed decisions regarding care and lead to better outcomes for patients living with your disease. We greatly appreciate your considering contributing your sample to the Arkana Biorepository and helping to advance kidney disease research.

If you have one of the following conditions and would like to participate, follow the instructions below:

  • Membranous glomerulopathy
  • Lupus nephritis
  • Membranous-like glomerulopathy with masked IgG kappa deposits
  • Fibrillary glomerulopathy


How to participate:

  1. Read carefully through the Informed Consent and Contact documents below.
  2. Ensure that you understand all aspects of the consent form, then sign and submit it.
  3. Once your consent form is received, the Biorepository staff will send you the human biologic sample collection kit needed for step 5.
  4. Once your human biologic sample collection kit is delivered, you will be contacted by a staff member of ExamOne in order to schedule your human biologic sample collection appointment. ExamOne will send a mobile phlebotomist to a location of your choosing (i.e. home or office) at the agreed-upon date/time.
  5. At the time of the appointment, please provide the collection kit contents to your mobile phlebotomist, and they will take care of the rest.


Note: Arkana Labs will cover the cost of mobile phlebotomy and shipping, so once you have completed your mobile phlebotomy appointment, your portion will be complete.
