The Rich History of Unilab

Our Story

The phrase family business has more than one meaning for Julio E. Cortes, President and CEO of Unilab. “At Unilab, we work very hard to produce the highest quality test results for all clients, coupled with the best level of customer service in the lab industry,” says Julio E. Cortes.

Julio attributes the company’s growth to excellent customer service as well as capitalizing on marriage and family trends, including that couples are waiting much later in their relationships to start families. With over 30 years of success, Unilab is the go-to company for a majority of local doctors, as well as doctors throughout the company’s expanded statewide service area.

A Struggle With Infertility

Why Unilab's Story Is Personal

Over 50 years ago, Julio's father and the founder of Unilab, Dr. Julio M. Cortes and his wife Eduvigis, were like many couples, longing for a child and struggling to make that dream a reality. They were experiencing infertility issues.


During that time, Dr. Cortes was working as a researcher at the Worcester Foundation for Experimental Biology in Massachusetts–the birthplace of reproductive science in the United States in the early 1960’s. Dr. Eugenia Rosenberg, a colleague in charge of clinical trials, approached Dr. Cortes about trying a new experimental fertility drug called Pergonal.

Dr. Cortes and his wife were more than willing to try this new drug. With good fortune, Eduvigis became pregnant after the first set of dosing. The birth of their son was truly unique and special as it marked the first single birth born from the fertility drug Pergonal in the United States. ​

Founding Unilab

Celebrating 30 years as a family owned laboratory.

In 1988, Dr. Cortes continued his quest for resolving the painful challenge of infertility by starting another lab called Unilab of Dade. 


With a well-established reputation in the field of endocrinology testing, he partnered with the first doctors to practice reproductive medicine in South Florida. The lab expanded and Dr. Cortes’ own son Julio began to take on a partnership role in the lab.


Years later, Julio and his wife would also experience difficulties getting pregnant, only now the resources were readily available and the couple was fortunate to receive assistance from the labs’ clients. This next generation couple would eventually give birth to two beautiful children.
