Urine sediment analysis can detect kidney and urinary tract diseases by analyzing blood cells, bacteria, urinary casts, etc., in urine samples. Urine sediment and dry chemistry analysis form urinalysis. Urinalysis, together with hematology and biochemistry analysis, are the three most common methods used in in-vitro diagnostic market. In 2010, the diagnostic urinalysis market in China was approximately $155 million, of which urine sediment analysis accounted for about 45% of the total, growing at an annual rate of over 30%.

Mindray expects to achieve synergies in the transaction by combining its strong engineering, manufacturing, sales and management platforms with Hyssen’s technology and expertise in urine sediment analysis. “We are excited about this transaction and believe that our collaboration will benefit both Mindray and Hyssen,” said Mr. Minghe Cheng, Mindray’s Chief Strategic Officer. “Hyssen’s products complement our current in-vitro diagnostic product offerings in urine dry chemistry, hematology and biochemistry.
