To assist the physicians in making a more accurate and reliable diagnosis to develop an appropriate treatment plan, we offer the services of two clinical laboratories, attending more than 9000 persons every year, carrying out over 16,000 exams. The basic tests offered include hematology, stool, urine, VDRL, helicobacter pylori, pregnancy, blood type, glucose level, malaria, total cholesterol, HDL y LDL, urea nitrogen, creatinine, triglycerides, uric acid, ASO y rheumatoid factor, with a cost averaging between Q10.00 and Q30.00 ($1.30 and $3.90) per exam. As with our other clinical services, these laboratories provide a quality, low cost service that would otherwise be unattainable for the people of our area. Patients are attended on a first come, first serve basis and results are given within 3 hours so patients have them readily available and can then go to the medical clinic. The clinical laboratories are attended by a laboratory assistant and 2 registered lab techs who are supervised by a medical technician, offering services that the patients have always reported as very good, expressing their complete satisfaction.
