+    "The Quantgene/Serenomica lab case IDs are unique identifiers for each of our samples. The samples also have our sample ID numbers, which are not unique.
+
+    Can you make sure the lab case ID numbers are still labeled on the tubes which are being sent to us?
+
+
+
+    Lastly, can you get us a full list of plasma samples on our research project (approx. 135, including the last 7 specimens we have been discussing) along with the lab case ID numbers and sample ID numbers? If a date of collection or lab receipt date is available that would also be helpful. I have several partial lists containing this information.
