Sichart equation
WebIf I am unclear as to whether or not this estimate makes sense, I send out a cystatin C. GFR can be estimated by 70.69 x CysC -0.931. If the two univariate estimates agree within 10%, then that is the eGFR. If there is disagreement, try to see which estimate is likely off. If this is not obvious, you may have to measure GFR in such a patient. WebAboutTranscript. The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
