Tests on the state list

This list does not break certification down by analyte. Ask the lab which tests it is certified for; the groups as written on the list are below.

• Named on the official list The state list names this analyte (or a column for it) for this lab.
• Group-level certification Certified for a parent group (e.g. 'Inorganics') that includes this analyte. Confirm the specific test with the lab.
• Partial group certification The list marks the group as 'Partial'. Confirm this analyte with the lab.
• Subcontracted The lab sends this analyte to another accredited lab (MDH 'X*').

LDH's chemistry list names 1 drinking-water analyte this lab is certified for (1 analyte/method entry). EPA lab ID TX02693, TNI ID TNI00037. Louisiana certifies this lab by reciprocity; its primary accreditation body is TX. LDH's chemistry list prints no phone number.

Before you send a sample

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Louisiana certification program.
