應用

• Clinical and laboratory features of urinary tract infections in young infants: Discusses diagnostic challenges and characteristics of urinary tract infections in infants, stressing the importance of accurate detection to guide treatment (Lo et al., 2018).


• Differentiating Kawasaki disease from urinary tract infection in febrile children with pyuria and C-reactive protein elevation: Focuses on differential diagnosis in pediatric care, which can influence the choice of nitrite tests for accurate and timely diagnosis (Han and Lee, 2018).


• Early features of Kawasaki disease with pyuria in febrile infants younger than 6 months: Addresses the overlap of urinary symptoms in Kawasaki disease, underscoring the utility of nitrite tests in complex cases (Yoon et al., 2018).

分析報告

应用测试符合

该MQuant^®亚硝酸盐测试（原MColortest^®）适用于使用简单易用的比色卡进行比色法检测。测试对象包括未处理样品，因此即使是混浊和有色的水样，也无需进一步制备就能用于分析。亚硝酸盐天然存在于土壤、水和食物中，必须密切监测饮用水和地下水以及工艺水、废水、水族馆用水中的亚硝酸盐。
该测试可用于：

• 地下水、地表水和海水
• 饮用水和矿泉水
• 水族馆水（淡水和海水）、水产养殖水
• 经过适当样品预处理的食品
• 经过适当样品预处理的土壤和肥料
• 锅炉及锅炉给水、冷却水
• 废水
• 电镀废水

分析方法
在酸性溶液中，亚硝酸根离子与对氨基苯磺酸反应形成重氮盐，它继而与N-(1-萘基)-乙二胺二盐酸盐反应形成紫红色偶氮染料。通过匹配测试液颜色与比色卡值，可半定量测定亚硝酸盐浓度。
