Yes. Temazepam is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. The LabX 12-panel screen includes a Benzodiazepines line, but how strongly a screen reacts to Temazepam varies, so a negative screen does not rule it out. Laboratory confirmation measures Temazepam specifically.
Temazepam is a benzodiazepine prescribed as a sleep medicine. It is also formed from diazepam in the body and is itself broken down into oxazepam.
Also known as or found in: Restoril.
Temazepam is prescribed for short-term treatment of insomnia.
Temazepam is measured by liquid chromatography with tandem mass spectrometry (LC-MS/MS), which separates the compounds in a sample and identifies each one by its mass. That is different from a rapid screen, which reacts to a family of drugs and can occasionally react to a related substance. The laboratory reports Temazepam as detected when its concentration is at or above the cut-off of 50 ng/mL, within a reportable range of 50–5,000 ng/mL. It is one of 8 compounds in the benzodiazepines and z-drugs family on the 76-drug confirmation panel.
The laboratory's confirmation report lists an approximate detection window of 1-4 days for Temazepam. Treat that as a rough guide only: how long any compound stays measurable varies with the amount taken, how often it is used, body composition, metabolism, kidney and liver function, and hydration. A laboratory result cannot be used to work out when a substance was taken.

Temazepam, nordiazepam and oxazepam can appear together after diazepam use, so a reviewer looks at the overall pattern rather than a single compound.
Prescription sedatives and sleep medicines and their metabolites. Standard screens detect individual benzodiazepines unevenly, so confirmation identifies each one.

Laboratory confirmation measures Temazepam specifically.
LabX reports Temazepam as detected at or above 50 ng/mL, and the method's reportable range is 50–5,000 ng/mL. A result below the cut-off is reported as not detected; it does not prove none was present.
The laboratory lists an approximate window of 1-4 days, but it varies with dose, frequency of use, metabolism and hydration, and cannot be used to tell when something was taken.
