What is a lot number?
A lot number is the unique identifier assigned to a batch of material that was produced, handled and tested as one unit; it links a vial to its certificate of analysis.
Why lot numbers matter
Analytical results describe a specific batch, not a product in general. The lot number is what connects the vial in your hands to the test results for the batch it came from. Without it, a certificate of analysis cannot be matched to anything.
GLP-3 RT lot numbers
Every GLP-3 RT vial label carries a lot number such as KB89232. The same number appears on the laboratory certificate and names the lot's page in the COA archive, for example /coa/kb89232/.
Lot numbers and laboratory reference numbers
The testing laboratory also assigns its own reference numbers to each submitted sample: accession number and search code. They are listed on each GLP-3 RT lot page with the lot number, so a certificate can be cross-checked with the laboratory.
