| Laboratory Concept | LabVantage Concept | Example |
| Register Incoming Samples | Sample Login is the process
of creating a Sample record in the LabVantage database.
Sample Login can optionally be performed using a Sample Template, which is essentially a clone of a predefined Sample, including all entities associated with the Sample. During Login, other entities (such as Batches or Requests) can also be associated with the Sample. |
I want to perform this test frequently, so
I create a Sample Template for my graphite Sample with the "scratch hardness"
Test Method as described in Analysis
Setup.
I now simply login a Sample based on this Sample Template. Login creates Sample "S-001" in the database and adds the Test Method as defined by the Sample Template. |
| Print Labels for Samples | Labels can be generated for the test samples using barcode printing software. | To identify the Samples throughout the testing process, I generate/print a barcode Label and attach it to the Sample container. |
| Receive Samples | Samples can be marked as Received during Sample Login or separately as a distinct step after Sample Login by scanning Label barcodes. | There is no need to have a separate receipt process for graphite Samples, so I choose to automatically Receive during Sample Login. |
| Add Tests | A Test Method provides a complete
set of instructions for conducting an analytical test, including any number
of Parameter Lists (such as for Preparatory testing), Specifications, and
other Test Methods.
A Test is a unique instance of a Test Method created when the Test Method is added to a Sample. This allows you to add the same Test Method to a Sample multiple times. |
Since I used a Template with Test Method to create a Sample, I don't need to add a Test here. |
| Assign Resources to Tests | An Analyst, Department, or Instrument can be assigned to the Test associated with the Sample. | I assign the Data Set (described below) to Mary. She can therefore enter data against it. |
| Enter Results | A Data Set is an instance
of a Parameter List that is associated with a Sample. A Data Item
refers to the combination of the value entered for a Parameter, and all
information defined by the Data Set (such as Limits and Calculations).
Results are entered for each Parameter, either manually (using Data Entry pages or Worksheets), or directly from an Instrument. |
Mary tests the graphite Sample and enters the results for the "hardness" and "temp" Data Items in the "scratch hardness" Data Set. |
| Review Test Results | Following Data Entry, results can be Reviewed.
Review offers the opportunity to view individual results, determine the
disposition of the Sample, and lets you decide whether to dispose of or
retain the Sample.
Use Retest and Remeasure to conduct additional testing. These create new instances of Tests and Data Sets that are used to record results of a repeat test or measurement. |
Review is required by John. He is dissatisfied
with the results and decides to Retest. The Retest adds a second instance
of the Test Method to the Sample. Mary does the Retest by entering new data
for the second instance.
John is then satisfied with the new results and Approves the Sample. |
| Generate COA | A Certificate of Acceptance PDF can be generated during Sample Review. If any associated Specifications failed, you can decide during Review whether or not to generate the Certificate. | John is satisfied with the Retest and generates the Certificate of Acceptance. |
