Abstract Purpose Erythrocyte sedimentation rate (ESR) is a widely used indicator of inflammation and a routinely done hematology investigation to monitor patients of autoimmune and infectious diseases. We aimed to compare the ESR results obtained by Roller 20LC automated instrument and standard reference Westergren method and analyzed the effect of anemia (hematocrit) on ESR measurements through the automated method. Methods We analyzed 1377 random anemic OPD patients (hematocrit [HCT] < 35%) for ESR levels measured by Roller 20LC using EDTA blood and Westergren method using citrated blood for a one and half year period from January 1, 2018 to June 30, 2019. Fabry’s formula was used to correct the Westergren ESR. Results The total number of samples after evaluation were divided into low (n = 232), intermediate (n = 417), high (n = 406), and very high range of ESR (≥100 mm/hr; n = 422). Mean difference between values of corrected and automated ESR for the low, intermediate, high and very high ESR range was 2.33 ± 5.03, 10.95 ± 8.04, 28.22 ± 19.11 and 43.3 ± 19.22 mm/hr, respectively. The 95% limit of agreement calculated by the Bland–Altmann analysis between the two methods for low-ESR range was −7.53 to 12.2 (highest correlation coefficient –0.65), while for very high ESR, range was −5.1 to 81.5 (least coefficient of 0.18) (p < 0.001). Conclusion In laboratories with high-sample load and where manual measurement may be tedious, the automated method of ESR measurement can safely replace the Westergren method for low-ESR values in patients with low hematocrit. While for high-ESR values, validation by the standard Westergren method may be needed.

Erythrocyte sedimentation rate (ESR) is the rate at which RBC sediment in a period of 1 hr. It is a common Haematology test that is a non-specific measure of inflammation and it became a common screening test worldwide for acute phase proteins and chronic diseases. The International Council for Standardization in Haematology (ICSH) recommended the Westergren method as the method of choice for ESR determination. TSC is almost exclusively used as the diluent of choice for setting up ESR, but some contemporary laboratories have resolved to use Normal saline (NS) as the diluent of choice while other set ESR using EDTA anticoagulated Blood (BLD) without any diluent. The objective of this study is to assess the comparison between saline diluted and undiluted EDTA with TSC as an anticoagulant in ESR detection and to find out any gender wise variations by using these anticoagulants. A total of 50 students were participated in this study. From each of the participants 5 ml of BLD was collected and it is then divided into 3 parts. 1.6 ml BLD to 0.4ml 3.8% TSC tube, 1.6 ml EDTA blood to 0.4 ml NS tube. 3rd tube with 2 ml EDTA BLD and set for ESR and obtained result within 1 hour. The Result is the mean +SD value of ESR were 19.48+5.7 mm/hr. in undiluted EDTA, 15.22+4.6 mm/hr. in saline diluted EDTA & 15.36+4.5 mm/hr. in TSC. The mean difference of ESR value between saline diluted EDTA with TSC BLD was 0 and it with undiluted EDTA was 4 mm /hr. The study indicates that there was a significant difference between ESR value with undiluted EDTA and TSC while diluted EDTA and TSC were there is no significant difference. The mean +SD of ESR value using undiluted, diluted EDTA and TSC in males were 16.20+3.3, 11.05+2.8, 11.29+2.6 and while it for females were 21.69+5.2, 17.36+3.8, 17.45+3.8 respectively. In conclusion, TSC is the best diluent to be used in contemporary lab to set ESR as compared to EDTA BLD. But we can use saline diluted EDTA as an alternative to citrate diluted BLD to set ESR and it also showed there is a gender wise variation in ESR using these anticoagulants.

BACKGROUND: The diagnosis of osteomyelitis is a key step of diabetic foot management. Procalcitonin (PCT) is a novel infection marker. This study aimed to investigate the diagnostic value of procalcitonin and other conventional infection markers and clinical findings in diagnosis of osteomyelitis in diabetic foot patients. METHODS AND MATERIALS: This diagnostic value study was carried out on ninety patients with diabetic infected foot ulcers admitted in Kashan Beheshti Hospital, 2016. After obtaining consent, 10 cc blood sample was taken for measuring serum PCT, CBC, ESR, CRP and FBS. Clinical characteristics of the wounds were noted. Magnetic resonance imaging of the foot was performed in all patients to diagnose osteomyelitis. All statistical analyses were done with the use of SPSS-16. RESULTS: PCT levels were 0.13 ± 0.02 ng/mili patients with osteomyelitis (n= 45) and 0.04 ± 0.02 ng/ml in patients without osteomyelitis (n= 45). PCT, Erythrocyte sedimentation rate and C-reactive protein was found significantly higher in patients with osteomyelitis (p< 0.001). The ROC curve was calculated for PCT. The area under the ROC curve for infection identification was 1 (p< 0.001). The best cut-off value for PCT was 0.085 ng/ml. Sensitivity, specificity, and positive and negative predictive values were 100%, 97.8%,97.8% and 100%, respectively. CONCLUSION: In this group of patients, PCT was useful to discriminate patients with bone infection. Also, Erythrocyte sedimentation rate and C-reactive protein can be used as a marker of osteomyelitis in diabetic patients.
