Websensitivity of the developed LC-MS/MS method was evaluated by these two parameters. The LOD and LOQ values obtained demonstrate that the present LC-MS/MS method is suitable for the analysis of lutein. Intra-day precision and accuracy are shown in table 3. Intra-day variations were within 0.31-1.7 5 %. Intra-day accuracy ranged from 100.4 % to ... WebA normal level of NT-proBNP is: - Less than 125 pg/mL for patients aged 0-74 years. - Less than 450 pg/mL for patients aged 75-99 years. If you have heart failure, the following NT-proBNP levels could mean your heart function is unstable: - Higher than 450 pg/mL for patients under age 50. - Higher than 900 pg/mL for patients age 50 and older.
