Albumin Reagent Kit (BCG Method)

Albumin is one of those analytes that tells a surprisingly large story from a very small sample. It is the most abundant protein in human plasma, making up roughly 60% of total serum protein, and its concentration reflects things as varied as liver function, nutritional status, kidney disease, and hydration. Low albumin can mean liver failure, malabsorption, or nephrotic syndrome. Elevated albumin can flag dehydration. It's one of the most frequently ordered biochemistry tests globally — which means the reagent that runs it needs to be reliable, reproducible, and available consistently. The Albumin Reagent Kit from Microsidd uses the Bromocresol Green (BCG) method, specifically the Doumas et al endpoint colorimetric approach. In plain terms: albumin in the sample binds to the BCG dye under pH conditions of 4.0 to 4.2, producing an albumin-BCG complex with a characteristic colour shift. The intensity of that colour, measured by the analyser at an absorbance peak of 625nm, is directly proportional to the albumin concentration in the sample. The kit is ready-to-use — no preparation steps, no mixing required before the assay. Results are generated in 3 minutes. The detection range runs from 0.130 g/dL to 7.5 g/dL, which covers everything from critically low albumin in acute liver failure to the upper limits of clinically relevant serum levels. The kit arrives as 2 x 50ml of liquid stable albumin reagent plus 1 albumin standard vial — everything needed to run and calibrate the assay. Reagents and the standard are both specially stabilized to ensure consistency across the kit's shelf life. The kit is compatible with semi-automated bench-top analysers and fully automated biochemistry analysers, making it usable across clinic labs, hospital biochemistry departments, and high-throughput reference laboratory settings. For laboratory reagent importers, medical distribution companies, and diagnostic supply chains across the Middle East, Africa, and Southeast Asia — albumin is a bread-and-butter biochemistry test. It is ordered alongside liver function panels, renal function panels, and nutritional assessments every day in every accredited laboratory. A reliable source for this reagent, priced competitively and backed by consistent supply, is worth more to a procurement manager than the occasional discount from an unreliable one. Sara Wellness exports laboratory reagents and biochemistry kits to buyers across multiple international markets. We understand cold-chain logistics, we understand CDSCO registration documentation, and we understand that laboratory procurement managers track expiry dates closely when evaluating suppliers. Every order we handle is accompanied by complete export documentation, and every cold-chain shipment leaves properly packaged for the journey. Fifteen years of this has taught us that the details matter more than the pitch. MOQs are flexible. Combined orders across multiple biochemistry reagent parameters move well and price well together.
