Propper Manufacturing

Propper Manufacturing is a long-established maker of diagnostic and laboratory products, and this collection centers on the tools primary care practices, gastroenterology offices, and clinical labs use for early colorectal cancer screening. At its core is the Seracult line of fecal occult blood tests (FOBT) — guaiac-based, visual-read slides that detect hidden blood in stool, one of the most common warning signs flagged during routine screening.

The Seracult Single Slide Test Kit (37100100) is a complete 100-test system, arriving with single slides, two 15 mL bottles of developer, and 100 applicators — everything a practice needs to collect stool samples and read results in-house without sending specimens out. Because these are guaiac tests, patients are typically advised to follow dietary and medication guidance in the days before collection to reduce false positives, and each slide is developed by applying the hematology reagent and observing for a color change that indicates the presence of blood.

When a lab burns through developer faster than slides, the standalone Seracult Hematology Reagent (37901500) keeps testing going without repurchasing full kits. This 15 mL liquid reagent is the developing solution paired with Seracult slides, so stocking it separately is a practical way to control cost per test and avoid downtime mid-screening cycle.

Buyers choosing an FOBT usually weigh read method, test volume, and shelf life. Seracult's visual-read format needs no instrumentation — results are interpreted by eye, making it well suited to offices without automated analyzers — and the kit-plus-refill structure lets you match ordering to your actual patient throughput.
