Are Blood Ketones A Better Predictor Than Urine Ketones Of Acid Base Balance In Diabetic Ketoacidosis?

Abstract Detection of ketonaemia is a key factor in diagnosing diabetic ketoacidosis (DKA). Measurement of urinary ketones via the nitroprusside reaction is the most commonly employed diagnostic test; however, near patient testing of blood ketones is now widely available. In the clinical setting we wished to compare the utility of urine and blood ketone measurements to predict acid base balance and need for admission in patients with type 1 diabetes. A retrospective study was performed on 52 patients referred to the metabolic or acute receiving units of a teaching hospital. Urine and capillary ketone measurements, blood gas analysis and/or venous bicarbonate measurement were analysed together with the clinical outcome of either admission or discharge of the patient. Capillary β-hydroxybutyrate measurement gave a strong negative correlation (r -0.771; p<0.001) with serum bicarbonate concentration. Urine ketone measurement showed a weaker negative correlation (r -0.493; p<0.001) with bicarbonate levels. There was no difference in the ability to predict hospital admission between blood ketone measurement and urine ketone measurement )positive predictive value 84.6% [95% confidence in Continue reading >>

    I've noticed for a while now that my urine smells different . . . i heard it would smell like ammonia? Mine smells like plastic wrap, like when you open a new CD and take the plastic off, you get that smell . . its fairly strong, and has only started happening since going primal, is it safe to assume i am in ketosis?

    99.99% its ketosis if you have been eating ketosis levels of carbs. If you have not been eating that level of carbs, you might have a problem.

Starting 2 weeks ago i dropped down to 100g of carbs a day, then ~5 days later i droped to under 50g per day. So i do believe i have been eating a ketosis level of carbs
