The interest in the clinical importance of serum magnesium level has just recently begun with the analysis and findings of abnormal magnesium level in cardiovascular, metabolic and neuromuscular disorder. Although the serum level does not reflect the body magnesium level, but currently, only serum magnesium determination is widely used. Erythrocyte magnesium is considered more sensitive than serum magnesium as it reflects intracellular magnesium status. According to NCCLS (National Committee for Clinical Laboratory Standards) every laboratory is recommended to have its own reference range for the tests it performs, including magnesium determination. The reference range obtained is appropriate for the population and affected by the method and technique. This study aimed to find the reference range of serum and plasma magnesium and also intracellular magnesium i.e. erythrocyte magnesium by direct method, and compare the results of serum and plasma magnesium. Blood was taken from 114-blood donor from Unit Transfusi Darah Daerah (UTDD) Budhyarto Palang Merah Indonesia (PMI) DKI Jakarta, consisted of 57 male and 57 female, aged 17 â 65 years, clinically healthy according to PMI donor criteria. Blood was taken from blood set, collected into 4 ml vacuum tube without anticoagulant for serum magnesium determination and 3 ml vacuum tube with lithium heparin for determination of erythrocyte and plasma magnesium Determination of magnesium level was performed with clinical chemistry auto analyzer Hitachi 912 by Xylidil Blue method colorimetrically. This study showed no significant difference between serum and heparinized plasma extra cellular magnesium. The reference range for serum or plasma magnesium was 1.30 â 2.00 mEq/L and for erythrocyte magnesium was 4.46 - 7.10 mEq/L.

Objective: To determine the glycated albumin profile during pregnancy with normal glycemic status. Methods: We recruited 60 pregnant women between 21 and 36 weeks of gestation. We conducted several laboratory tests, such as glycated albumin, blood glucose, and albumin. These parameters were compared among four groups of gestational age (21-24 weeks, 25-28 weeks, 29-32 weeks, and 33-36 weeks) using ANOVA or Kruskal-Wallis test continued by Post-hoc test. Results: Glycated albumin was not statistically different among the groups. Albumin level of 33-36 weeks of gestation women (3.6 (SD 0.2) g/dl) was lower than 21-24 weeks of gestation women (3.8 (SD 0.2) g/dl). Conclusion: Glycated albumin level is not affected by gestational age. Therefore, glycated albumin may be used as glycemic status indicator during pregnancy from 21 to 36 weeks.

Background: Chronic heart failure (CHF) is a slowly progressive disease with high morbidity and mortality; therefore, the management using pharmacological treatments frequently fails to improve outcome. Enhanced external counterpulsation (EECP), a non-invasive treatment, may serve as alternative treatment for heart failure. This study was aimed to evaluate the influence of EECP on myeloperoxidase (MPO) as inflammatory marker as well as cardiac events outcome.Methods: This was an open randomized controlled clinical trial on 66 CHF patients visiting several cardiovascular clinics in Manado between January-December 2012. The subjects were randomly divided into two groups, i.e. the group who receive EECP therapy and those who did not receive EECP therapy with 33 patients in each group. Myeloperoxidase (MPO) as inflammatory marker was examined at baseline and after 6 months of observation. Cardiovascular events were observed as well after 6 months of observation. Unpaired t-test was use to analyze the difference of MPO between the two groups, and chi-square followed by calculation of relative risk were used for estimation of cardiovascular event outcomes.Results: MPO measurement at baseline and after 6 months in EECP group were 643.16 ± 239.40 pM and 422.31 ± 156.26 pM, respectively (p < 0.001). Whereas in non EECP group, the MPO values were 584.69 ± 281.40 pM and 517.64 ± 189.68 pM, repectively (p = 0.792). MPO reduction was observed in all patients of EECP group and in 13 patients (48%) of non-EECP group (p < 0.001). Cardiovascular events were observed in 7 (21.21%) and 15 (45.45%) of patients in EECP and non-EECP groups, respectively (p = 0.037).Conclusion: EECP therapy significantly decreased the level of MPO as inflammatory marker and this decrease was correlated with the reduction of cardiovascular events in CHF patients.

Thyroid-Stimulating Hormone (TSH) is an important parameter in diagnosing thyroid disease which uses serumaccording to the World Health Organization's (WHO) recommendations. The use of plasma can help improve the TurnAround Time (TAT); however, the discrepancy with serum is unknown. A cross-sectional study using 89 blood samples wasperformed to compare TSH levels using serum tubes with clot activator (Tube I), plasma tubes with heparin (Tube II), andplasma tubes with heparin-gel separator (Tube III); and to overview of TSH levels according to gender and age. The medianof TSH levels in Tubes I, II, and III were 1.380 (0.032-7.420) μIU/mL, 1.380 (0.030-7.480) μIU/mL, and 1.360 (0.030-7.460)μIU/mL, respectively. There were no statistically significant differences in TSH levels of the three tubes. The median TSHlevels differences of Tubes II and III compared to the tube I were -0.9% (-7.2-2.2) and -1.7% (-8.0-1.6), respectively.Measurement bias observed in this study was following the specified desirable bias according to Ricos. The median TSHlevels of the male and female groups were 1.500 (0.032-4.250) μIU/mL and 1.345 (0.058-7.420) μIU/mL, respectively. MedianTSH levels of 31-40 years old age group and >61 years old age group were 1.190 (0.609-3.240) μIU/mL and 1.730 (0.088-5.760) μIU/mL, respectively. Specimens from three tubes could be used to examine TSH levels. Measurement of TSH levelsshowed a higher median in the male and older group.

Pendahuluan. Skin Prick Test (SPT) merupakan baku emas diagnosis alergi, tetapi tidak dapat dilakukan pada kondisi tertentu seperti dermatografisme, hamil, tidak dapat lepas obat antialergi, sehingga pemeriksaan IgE spesifik menjadi pilihan. Di Indonesia belum ada data perbandingan pemeriksaan IgE spesifik dengan SPT. Penelitian ini dilakukan untuk menentukan sensitivitas, spesifisitas, PPV, NPV, LR+ dan LR- pemeriksaan IgE spesifik menggunakan analisis immunoblot. Metode. Penelitian menggunakan desain potong lintang. Subjek penelitian adalah pasien poliklinik alergi imunologi. Pengambilan sampel dengan metode non-probability sampling dengan teknik consecutive sampling. Analisis dilakukan terhadap alergen tungau debu rumah (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis) dan kecoa. Hasil. Seratus subjek yang memenuhi kiteria masukan dan tolakan (76% perempuan, rerata usia 38.9 tahun) ikut serta dalam penelitian ini. Sensitivitas empat alergen bervariasi dengan rentang 32.4%-76.8%, spesifisitas 68.0%-85.7%, PPV 54.5%-94.5%, NPV 46.2%-65.3%, LR+ 1.8-5.0, dan LR- 0.3-0.8.Sensitivitas pemeriksaan IgE spesifik cukup baik pada tiga tungau debu rumah tetapi rendah pada kecoa; spesifisitas dan PPV bervariasi cukup sampai baik; NPV cukup baik. Simpulan dan Saran. Uji diagnostik IgE spesifik tungau debu rumah menunjukkan hasil cukup baik. Pemeriksaan IgE spesifik tidak dapat digunakan untuk skrining alergi kecoa.Background. Skin Prick Test (SPT) is considered as gold standard for diagnosis of allergy, but cannot be performed in some conditions such as dermatographism, pregnancy, and unable to abstain from antiallergy drugs. In these conditions, specific-IgE test is a test of choice. But there is no comparison data on specific IgE test with SPT in Indonesia. This study was to investigate sensitivity, specificity, PPV, NPV, LR+, and LR- of specific-IgE test of immunoblot assay kit. Method. The study was cross-sectional. Subjects were patients from allergy-immunology clinic who fulfilled inclusion and exclusion criteria. Sampling was performed using non-probability sampling method with consecutive technique. Analysis was performed for house dust mite allergen (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis) and cockroach. Result. Hundred subjects (76% was female, average age of 38.9 years) were involved. Sensitivity of four allergens were varied with range 32.4%-76.8%, specificity 68.0%-85.7%, PPV 54.5%-94.5%, NPV 46.2%-65.3%, LR+ 1.8-5.0, and LR- 0.3-0.8. Sensitivities of specific-IgE for three species of house dust mite were moderate, but low for cockroach; specificities and PPVs were moderate to high; NPVs were moderate. Conclusion. Diagnostic test of specific-IgE with house dust mite allergen shows adequate result. Specific IgE test cannot be utilized for screening of cockroach allergy.Â
