A more rapid test capable of accurately predicting the results of a 24-hour urine collection would be valuable.ДЄn alternative method for quantitative evaluation of proteinuria is the measurement of the albumin: creatinine ratio (ACR) in a spot urine sample, which avoids the influence of variations in urinary solute concentration and provides a more convenient and rapid method to assess protein excretion. However, 24-hour urine collection is time consuming, inconvenient, and not always reliable because of the difficulty in collecting the sample correctly. Measurement of protein excretion in a 24-hour urine collection has been the longstanding вЂњgold standardвЂќ for the quantitative evaluation of proteinuria in pregnancy. 2 In women presenting with elevations in blood pressure in the latter half of pregnancy (defined as a sustained elevation in blood pressure of в‰Ґ 140 mm Hg systolic and/or в‰Ґ 90 mm Hg diastolic), detailed laboratory evaluations are essential to determine whether a patient has a diagnosis of preeclampsia, including assessment of proteinuria, platelet count, and liver and renal function testing.

1, 2 The latest analysis by the World Health Organization suggests that, in developed countries, 16% of maternal deaths in pregnancy were a result of hypertensive disorders. Hypertensive disorders complicate 5% to 10% of all pregnancies and are associated with significant maternal morbidity and mortality. Conclusions: Compared with 24-hour urinary protein excretion, the spot urinary ACR may be a simple, convenient, and accurate indicator of significant proteinuria in women with preeclampsia. The optimal spot ACR cutoff point was 22.8 mg/mmol for 0.3 g/24 h of protein excretion (mild preeclampsia) with a sensitivity and specificity of 82.4% and 99.4%, respectively, and 155.6 mg/mmol for 2 g/24 h of protein excretion (severe preeclampsia) with a sensitivity and specificity of 90.6% and 99.6%, respectively. Results: A strong correlation was evident between the spot ACR and 24-hour urinary protein excretion ( r =. Receiver operating characteristic curve analysis was used to determine the best cutoff values of the spot ACR for mild preeclampsia (proteinuria в‰Ґ 0.3 g/24 h) and severe preeclampsia (defined in China as proteinuria в‰Ґ 2 g/24 h). The correlation between the spot ACR and 24-hour urine protein excretion was assessed, and the diagnostic value of ACR was expressed in terms of specificity and sensitivity. ACR was determined in a spot midstream urine sample and the amount of protein excretion was quantified in a 24-hour urine collection performed the following day. Methods: ACR and 24-hour urinary protein excretion were measured in 50 consecutive patients with preeclampsia.

Within medical reports and communication micrograms are commonly referred to with the symbol mcg. On Windows, keep the Alt key depressed whilst you type the digits 2 3 0. To type the symbol Ој on a Mac, press the вЊҐ Option + m keys together. Microgram is a unit in the metric system and its symbol is Ојg.
