The objective of the present study was to determine the effectiveness of the Acaro Test technique in detecting Demodex folliculorum. The methodology used was descriptive, prospective, and cross-sectional. A population of 150 patients was selected, all of whom were requested for a Demodex folliculorum screening, and both the depilation technique (Gold Standard) and Acaro Test were applied. The sample consisted of 120 positive results, with both techniques performed. The results showed that the Acaro Test technique is effective in detecting Demodex folliculorum, producing the same number of positive samples as the Gold Standard. The Acaro Test technique also revealed the presence of various developmental stages, not just the adult stage. In conclusion, the described technique is an effective alternative with high sensitivity and specificity (100%), easy to apply, and provides patient satisfaction, particularly in children, thus increasing the likelihood of obtaining more positive results. Additionally, it allows for longer sample storage and observation of the mite in its different developmental stages.

Efficiency in the alarm signs of immature cells reported from the automated hematology analyzer of the “Beckman Coulter 600“ equipment with the revision of the peripheral plate in adult patients, Hospital Nacional Hipólito Unanue, El Agustino Peru, December 2019 - February 2020

The objective was to determine the efficiency of immature cell alarms reported by the automated hematological analyzer in the "Beckman Coulter 600" with peripheral smear review in adult patients at the National Hipólito Unanue Hospital from December 2019 to February 2020. A total of 489 reports of immature leukocytes were evaluated. The efficiency, sensitivity, specificity, positive and negative predictive values, as well as the Kappa concordance index, were calculated. An efficiency of 95.3%, sensitivity of 70.0%, specificity of 95.8%, positive predictive value of 25.9%, and negative predictive value of 99.4% were found. The Kappa concordance index was 0.36. The efficiency level of the immature cell alarms in the central laboratory, reported by the Beckman Coulter equipment at the National Hipólito Unanue Hospital, was 95.3%. The sensitivity and specificity of the alarms of the Beckman Coulter automated equipment were 70.0% and 95.8%, respectively. The positive and negative predictive values of the alarms were 25.9% and 99.4%. The degree of concordance between the immature cell alarms of the automated hematological analyzer and the peripheral smear was 0.36, classified as mild.
