## Laboratory Evaluation Help Center

- Step-by-Step Guidance for **“How to Fill Out the** **Lab Data Form”**

## WARNING!

- The forms available on the LEP website are **not yet live**. They are mock-ups of the upcoming web-based forms that will feed directly to our database.
- Do not enter data into these forms while on the web – all entries will be lost. Instead, copy the form to your computer and use them as a template for now.

## No Proficiency Test Sample Data?

- If you (the laboratory) do not participate in round-robin or blind proficiency testing studies for the analyses requested, you will not be able to fill out this data form. You do not need to review this training if you don’t have blind test data.
- If you don’t have blind test data, please contact the USGS Project Chief as soon as possible to arrange for blind sample submission.
- In any case, please **DO** send in the _[Method Data Table ](file:///C:/Documents%20and%20Settings/bfconnor/Local%20Settings/Temporary%20Internet%20Files/Content.IE5/6TCFAPSX/lab_methodform.xls)__even if you don’t have any performance data._

## Lab Form – DATA

- Continue with this training IF you have blind data to submit to USGS.
- Table 2 is used for passing the results of double blind studies to the USGS project chief.

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Ask PT provider for flat file or Excel Spreadsheet

- Most Proficiency Test Sample providers will provide you and your customers with a flat file (.txt) or an Excel spreadsheet of your results if you ask for it.
- Use this offer to save yourself time or errors re-typing this information where available.

## Lab Form – DATA

- Copy in the Analyte Names, Pcode, Matrix, and Method (if populated) from the Project Form data provided you by the USGS Project Chief.
- If the USGS Project Chief did not fill in the _method_ field, they are looking for your suggested method to best match their analyte list, matrix, and concentration ranges expected. **Please provide a suggested method!**

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
|  |  |  |  |  |  |  |  |  |  |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form – DATA

- “Date Analyzed” is the date of analysis of a Test Sample. This is necessary to assure that USGS has your most recent data.

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form – DATA

- “Sample Type” is the kind of blind sample reported. Examples include WS and WP studies, USGS Standard Reference Samples, or Environment Canada studies (to name a few).

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form – DATA

- “Study Name” is the name of the specific study, such as WS109, WP 131, or M-176 .

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form –DATA

- Reported Value is the numerical result of the test.

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form –DATA

- “Units” is the concentration as reported.

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |

## Lab Form –DATA

- “True Value” is the value to compare with the “Reported Value”. It is the expected concentration.

| Analyte |  P code | Matrix | Method | Date Analyzed | Sample Type | Study Name | Reported Value | Units | True Value  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| example 2 | 45678B | GW | SM1234 | 2/2/2006 | USGS Round robin | Fall 06 | 1 | mg/L | 0.98 |
