International Patients:  Standards of Care vary from country to country.  Because you will be receiving care in the U.S.A., you will be required to meet our Standards of Care.  Please have your physician provide you with all prenatal labs, the date done and results so we do not have to redo the labs.

U.S. and International Patients:  From time to time, Dr. La may need to order additional labs in order to treat a new or existing problem.  Our office will provide you with an explanation of why the lab is necessary and the cost.
