Horiba ABX Pentra LDL Direct CP Reagent – ~100 Tests – Pentra 400 / C400 (P/N 1220001638)

What is it:

The Horiba ABX Pentra LDL Direct CP (P/N 1220001638, REF A11A01638) is a genuine HORIBA reagent for the direct measurement of LDL (low-density lipoprotein) cholesterol on the ABX Pentra 400 / Pentra C400 clinical chemistry analyzer. It uses a homogeneous (direct) method and is supplied as a ready-to-use bi-reagent cassette (Reagent 1: 28 mL · Reagent 2: 10 mL), good for approximately 100 tests. For professional in vitro diagnostic use.

Part numbers:

• Catalog P/N: 1220001638
• Box REF: A11A01638

What it's used for:

LDL Direct CP measures LDL cholesterol directly in serum and plasma — a core component of the lipid panel used in cardiovascular risk assessment and the management of lipid disorders. Unlike calculated LDL (the Friedewald estimate derived from total cholesterol, HDL, and triglycerides), this is a direct homogeneous assay that measures LDL-cholesterol on the analyzer without a separate precipitation step — more reliable in patients with elevated triglycerides or non-fasting samples, where calculated LDL can be inaccurate. Because LDL is a high-volume lipid test, this is a routinely reordered reagent, used together with the LDL calibrator (P/N 1220001678) and appropriate controls.

What's included:

• 1 × ABX Pentra LDL Direct CP bi-reagent cassette
• Reagent 1: 28 mL · Reagent 2: 10 mL
• Approximately 100 tests per cassette
• Manufactured by HORIBA ABX SAS

Compatible analyzer:

• ABX Pentra 400 (Pentra C400) Clinical Chemistry Analyzer

This is the LDL measurement reagent for the Pentra 400 / C400. It is distinct from the LDL Calibrator (P/N 1220001678, which standardizes the assay) and from lipid controls (which verify QC). Order the LDL item your task requires. 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 LDL Direct CP used for?

It's the reagent that measures LDL cholesterol directly on the Pentra 400 / C400. LDL is a core part of the lipid panel used in cardiovascular risk assessment and lipid-disorder management.

What does "Direct" mean here?

It's a direct (homogeneous) LDL assay — the analyzer measures LDL-cholesterol directly, rather than calculating it with the Friedewald equation from total cholesterol, HDL, and triglycerides. Direct LDL is more reliable in patients with high triglycerides or non-fasting samples, where the calculated estimate can be inaccurate.

Which analyzer is P/N 1220001638 compatible with?

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

How many tests does one cassette provide?

Approximately 100 tests. Actual yield depends on your calibration and QC frequency.

Is this the reagent or the calibrator?

This is the reagent that runs the LDL test. The LDL Calibrator (P/N 1220001678) is a separate product used to calibrate the assay. Most labs need both — order the one your task requires, or both if you're setting up the test.

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 A11A01638; distributors order it as P/N 1220001638. They're the same product — we list both so you find this page from either number.
