The Story of a Laboratory, Appendix: Four Lab Reports

Appendix: Four Lab Reports

This report attempts to focus on the “big picture”, the concepts of public health that guided the work of the laboratory during each period. The day to day work of any lab, however, involves receiving specimens, testing them as accurately as possible, and reporting the results in a timely manner so that the data may be acted upon. This appendix presents annual reports of the Greenwich Department of Health Laboratory from four different periods in its existence, so that the development in its operations may be traced.

This is the first Annual Report, and it presents a picture of Dr. Bennett multi-tasking as a sanitarian (inspecting dairies, abating nuisances, overseeing fumigations of homes of patients with communicable diseases), a physician (hospital visits) and a bacteriologist, performing Widal examinations for syphilis, sputum examinations for tuberculosis, blood smears for malaria, and many tests for diphtheria.

Total                                                                                 4837

Thirty-five years later, Mr. Bozza’s work still concentrates on diagnostic bacteriology, with much less diphtheria work, more sexually transmitted diseases, gastrointestinal problems (typhoid, dysentery), tuberculosis, streptococcal infections which can cause scarlet fever, a disease of the heart, and testing for Vincent’s organisms (causing “trench mouth”, possibly referrals from the Dental program). A decade earlier the lab was testing for Vincent’s organisms at the rate of about 150 per year. These statistics reflect the beginnings of the control of infectious diseases due to the use of vaccines and antibiotics, and of concern for prevention, in the testing of restaurant eating utensils.

Twenty-five years later, this report demonstrates a major shift in the laboratory’s work. A huge number of air pollution measurements are reported, and a large number of water pollution tests as well. Mrs. Morrison and her crew have begun reporting examinations as well as the number of specimens, as a water sample might be tested for a dozen different bacteriological and chemical parameters, for example. One can see a shift to concern for chronic disease (diabetes screening) and prevention (hemoglobin screens, monitoring the distribution water for fluoride, which had been added to the water to prevent tooth decay since 1952) as well.

Greenwich switched its annual reports to reporting by fiscal year in 1963.

Mr. Serafin’s report 35 years later shows that the laboratory has shifted away from clinical diagnostic procedures and now focuses on environmental health and prevention. The laboratory tests public and private drinking water sources for chemical and bacteriological contamination, and monitors inland and coastal waters of the town for pollution. A large number of ticks are being tested annually for Lyme disease and babesiosis, and homes are tested for the presence of radon. Clinical activity focuses on screening children for hemoglobin and blood lead, and providing cholesterol testing to the public, often as part of nutrition education programs. The laboratory now uses POC (Point-of-Care) technology, which allows the test results to be given to the patient while they are still in the lab, allowing better opportunities for health education. Not reflected in the statistics are the laboratory’s activities in emergency preparedness and the dissemination of information regarding the re-emergence of the historic public nuisance of pesticide-resistant bedbugs, a legacy of the overuse of pesticides in the past.
