The current study aimed to introduce key ethical issues related to laboratory-based diagnostics that any individual may encounter during the provision of healthcare services. In a systematic review, relevant studies published on electronic databases including the PubMed, Scopus, Web of Science, Medline and Cochrane Library were collected for the years 1975 to 2020. The ethical issues related to clinical laboratories diagnosis and patients, colleagues, and society in different phases of laboratory testing were surveyed in this study. Considering ethical issues must be prioritized in each clinical laboratory for better dealing with clients, collaborators, and the community.

Strongyloidiasis is a frequent misdiagnosed parasitic infection in the world that caused by Strongyloides stercoralis. In Iran, the disease is predominantly reported from warm and humid climate provinces. The patient was a 54-yr-old man, originated from Khuzestan Province with a history of pemphigus and diabetes that was treated with high-dose of corticosteroid drugs before admission in a non-private hospital in Shiraz, Iran in 2014. After different primary diagnosis and administrating of several drugs, endoscopy and histopatholgical biopsy revealed a massive S. stercoralis infection in the duodenal mucosa and gastric wall. In spite treating with anti-helminthic drugs in the last days, due to using different steroid drugs, clinical manifestations of the patient were exacerbated and he was expired on the seventeenth day due to severe dyspnea. Physicians’ awareness and using various diagnosis methods like serology, endoscopy, and biopsy should be considered in the endemic areas. In suspicious cases, anthelmintic drugs should be started before the initiation of immunosuppressive therapy.

More than one hundred countries face the problem of malaria disease. Studies have indicated that thalassemic individuals are relatively more resistant to malaria. The present research set out to investigate this hypothesis in Iraushahr where these is a high prevalence of moralia. The goal of this study is to compare the prevalence of malaria in thalassemic individuals with non- thalassemic ones in Iranshahr. In this case-control study 100 thalassemic individuals (case) and 100 non-thalassemic case (control) were selected. In addition to serum specimen, their blood sample from their fingertips were also taken to prepare peripheral blood smear. The tests were performed on 200 random samples in July (the peak time of malaria transmission). In this study, both indirect immuno flurecance Assay (IFA) and direct amear technique were used. The data were analyzed in SPSS software using descriptive and analytical statistics including T- test, chi-square and ANOVA. In IFA 20 subjects had positive titer while 80 ones had negative titer. Direct microscopic examination indicated that these, 20 cases had malaria parasite, 10 of whom were affected by p. vivax and 10 whit p. falciparum. In the non-thalassemic people (control group), 75 subjects had positive titers and 25 had negative titer. With respect to the direct smear anamination in non-thalassemic subjects, 18 had malaria parasite, of whom 7 had p.falsiparium and 11 had vivax. The results of malaria antibody titer indicated that the history of being affected by malaria the thalassemic subjects was 92% less than the non-thalassemic ones and this difference was statistically, significant (p<0.05) however, no significant relationship was found in terms of the results of direct microscopic examination and Ginsastaining. Since thalassemic people are more resistant againt malaria futhure researches are required to investigated the resistance to malaria in other blood disorders.
