Horiba ABX Pentra Urea CP (BUN) Reagent – ~220 Tests – Pentra 400 / C400 (P/N 1220001641)

What is it:

The Horiba ABX Pentra Urea CP (P/N 1220001641, REF A11A01641) is a genuine HORIBA reagent for measuring urea — also reported as blood urea nitrogen (BUN) — on the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It uses an enzymatic UV method (urease / glutamate dehydrogenase) and is supplied as a ready-to-use bi-reagent cassette (Reagent 1: 60 mL · Reagent 2: 15 mL), good for approximately 220 tests. For professional in vitro diagnostic use.

Part numbers:

• Catalog P/N: 1220001641
• Box REF: A11A01641

What it's used for:

Urea CP measures urea (BUN) in serum, plasma, and urine — a core renal-function test used to assess kidney function and to help differentiate causes of azotemia. The assay uses an enzymatic UV method: urease hydrolyzes urea to ammonia, which glutamate dehydrogenase then consumes in a coupled reaction, producing a measurable change in UV absorbance proportional to the urea concentration. Because urea/BUN is a high-volume renal-panel test, this is a routinely reordered reagent, used together with the appropriate calibrator and controls.

What's included:

• 1 × ABX Pentra Urea CP bi-reagent cassette
• Reagent 1: 60 mL · Reagent 2: 15 mL
• Approximately 220 tests per cassette
• Manufactured by HORIBA ABX SAS

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer

This is the urea (BUN) measurement reagent for the Pentra 400 / C400. "Urea" and "BUN" (blood urea nitrogen) refer to the same analyte — this reagent covers both. It's distinct from the calibrator and controls used to standardize and monitor the assay. Not for use with non-HORIBA instruments.

Storage & shipping note:

Store refrigerated (2–8°C). Ships cold-chain with priority handling. Non-returnable once shipped.

FAQs:

What is the Horiba ABX Pentra Urea CP used for?

It's the reagent that measures urea — reported as BUN (blood urea nitrogen) — on the Pentra 400 / C400 using an enzymatic UV method. Urea/BUN is a core renal-function test used to assess kidney function.

Is "Urea" the same as "BUN"?

Yes — they measure the same analyte. "Urea" is the common international term and "BUN" (blood urea nitrogen) is the term used widely in U.S. labs. This reagent covers both; results can be reported either way depending on your analyzer settings.

Which analyzer is P/N 1220001641 compatible with?

The HORIBA ABX Pentra 400 / Pentra C400 clinical chemistry analyzer.

How many tests does one cassette provide?

Approximately 220 tests. Actual yield depends on your calibration and QC frequency.

What method does it use?

An enzymatic UV method using urease and glutamate dehydrogenase — urease releases ammonia from urea, which is consumed in a coupled reaction producing a UV absorbance change proportional to the urea concentration.

Does it need refrigeration?

Yes. Store refrigerated at 2–8°C, and the product ships with cold-chain handling.

What's the difference between the box REF and the catalog number?

The box shows REF A11A01641; distributors order it as P/N 1220001641. They're the same product — we list both so you find this page from either number.
