ISO 6888-3:2003规定了使用最可能数（MPN）技术对凝固酶阳性葡萄球菌的计数和检测的水平方法。适用于 用于人类消费和饲养动物的产品，以及 食品生产和食品处理领域的环境样品。 这种方法建议用于葡萄球菌预期受到压力且数量较少的产品，例如干燥产品。凝血酶阳性葡萄球菌主要为金黄色葡萄球菌，但中间葡萄球菌和一些葡萄球菌菌株也产生凝固酶

ISO 6888-3:2003 specifies a horizontal method for the enumeration and detection of coagulase-positive staphylococci, using the most probable number (MPN) technique. It is applicable to products intended for human consumption and the feeding of animals, andenvironmental samples in the area of food production and food handling. This method is recommended for products where staphylococci are expected to be stressed and in low numbers as, for example, in dried products. Coagulase-positive staphylococci will primarily be Staphylococcus aureus but Staphylococcus intermedius and some strains of Staphylococcus hyicus also produce coagulase.
