Frequently Asked Questions
Answers to common questions about amniotic membrane products, ordering, and clinical use.
What is amniotic membrane?
Amniotic membrane is the innermost layer of the placenta, composed of a basement membrane and stromal matrix. It has been used in medical applications for over 100 years due to its unique properties: it provides a natural scaffold for tissue repair, contains growth factors, and has anti-inflammatory and anti-scarring properties.
What are the indications for amniotic membrane?
In ophthalmology, amniotic membrane is used for corneal epithelial defects, corneal ulcers, limbal stem cell deficiency, pterygium surgery, chemical burns, and conjunctival reconstruction. In wound care, it is used for chronic wounds including diabetic foot ulcers, venous stasis ulcers, and pressure injuries.
What is the difference between cryopreserved and dehydrated amniotic membrane?
Cryopreserved amniotic membrane is stored at -80C and retains the highest level of growth factors and natural extracellular matrix structure. Dehydrated amniotic membrane is processed using low-heat technology to allow room temperature storage with a longer shelf life (24 months vs. 12 months), though it may have reduced growth factor content. Both formats have demonstrated clinical efficacy in published studies.
How should I store cryopreserved amniotic membrane?
Cryopreserved amniotic membrane must be stored in a -80C ultra-low temperature freezer. Do not refreeze after thawing. Store products away from the freezer door to avoid temperature fluctuations. Monitor freezer temperature with a calibrated thermometer and maintain a temperature log.
What is the shelf life of your products?
Cryopreserved products have a shelf life of 12 months from the date of manufacture when stored at -80C. Dehydrated products have a shelf life of 24 months when stored at room temperature (2-25C). Always check the expiration date on the package before use.
Do you offer samples for evaluation?
Yes, we offer sample products for qualified healthcare professionals to evaluate in their practice. Contact our team through the contact form to inquire about sample availability. Samples are provided at our discretion based on practice type and intended use.
What are the contraindications for amniotic membrane use?
Contraindications may include active ocular or wound infection, known hypersensitivity to the product or its components, and certain autoimmune conditions. Healthcare providers should review the product insert for complete contraindications, warnings, and precautions before use.
How do I dispose of unused amniotic membrane?
Unused amniotic membrane should be disposed of according to your facility's biomedical waste and tissue disposal policies. Cryopreserved products should not be thawed and refrozen. Contact our team if you have specific questions about product disposal.
What is your return policy?
Due to the nature of tissue products, we cannot accept returns of products that have left our facility. If you receive a product that is damaged or defective, contact us immediately for replacement. Quality issues should be reported within 48 hours of receipt.
How do I establish an account?
To establish an account, complete the contact form with your practice information, including your medical license number and DEA number (if applicable). Our team will verify your credentials and contact you within 1-2 business days to complete account setup.
