Solomon Park Research Laboratories, Inc. has been a leading biotechnology company since 1984, providing high-quality serum and plasma blood products to researchers, metrology experts, and equipment manufacturers. Our blood products are essential for developing quality controls, establishing standards, and creating white-label calibrators and controls. We use the CLSI C37-A procedure, developed in partnership with the Centers for Disease Control and Prevention, to ensure the highest quality products that are nearly indistinguishable from human test samples.
