Tosoh AIA-PACK PROG III Sample Diluting Solution – AIA-360 / 600 II / 900 (Cat. No. 0025540)

What is it:

The Tosoh AIA-PACK PROG III Sample Diluting Solution is a genuine Tosoh reagent used to dilute patient samples that read above the assay's upper measuring range on the Progesterone III immunoassay. It's supplied ready to use.

Part numbers:

• Cat. No.: 0025540
• Also searchable as (previous Tosoh part numbers): 025540, 25540

What it's used for:

When a patient's progesterone level exceeds the PROG III assay's linear range, this diluting solution is used to dilute the sample before re-running it, so the analyzer can report an accurate result instead of an out-of-range flag. It's assay-specific to Progesterone III — not interchangeable with PROG II or other hormone assay diluents.

What's included:

4 x 4 mL. Manufactured by Tosoh Corporation.

Compatible analyzers:

• Tosoh AIA-360
• Tosoh AIA-600 II
• Tosoh AIA-900

FAQs:

What is the Tosoh AIA-PACK PROG III Sample Diluting Solution used for?

It dilutes patient samples that come back above the Progesterone III assay's measuring range, so the analyzer can generate an accurate reportable result on the re-run.

Is this the same as the PROG II diluting solution?

No. PROG III has its own dedicated sample diluting solution (Cat. No. 0025540). If you're running an earlier assay generation, let us know and we'll confirm the correct part.

Which analyzers is Cat. No. 0025540 compatible with?

Confirmed for the AIA-360, AIA-600 II, and AIA-900. If you're running an AIA-1800 or AIA-2000, send us your setup and we'll confirm before you order.
