Best urine/blood test for diabetes insipidus?

Best urine/blood test for diabetes insipidus?

Vasopressin.: Diabetes insipidus is due to lack of urine concentrating ability. This is from insufficient ADH or antidiuretic hormone due to various causes. This is called central diabetes insipidus. This has high urine volume, low urine osmolality, and migh intake of fluids. Argenine vasopressin or avp given to these patients causes a >9% rise in urine osmolality. In normal patients, it is <9%. ...Read more

How are diabetes insipidus and diabetes mellitus different?

How are diabetes insipidus and diabetes mellitus different?

Very different: Diabetes mellitus is the typical "diabetes" that we are familiar with. It's caused by an Insulin problem (too little or just not working well (resistance)) causing elevation in blood sugar. Diabetes insipidus is a water problem characterized by lots of urination and high sodium level. It's caused by an ADH (vasopressin) (antidiuretic hormone) problem (too little or just not working well). ...Read more

Life-threatening: due to effects on electrolytes (sodium). If it isn't low, or inappropriate amounts in urine (sodium pee'd out, when it should be held in) then it isn't diabetes insipidus. Vitamin B12 deficiency is from zero in the diet (strict vegan diet), or from malabsorption. If meat in diet, then there is zero reason to take b12 by pill--doesn't get in, then pill won't help. ...Read more

Why is urine osmolality low in post renal failure?

Why is urine osmolality low in post renal failure?

Need time to heal: Acute kidney failure involves damage to the cells lining the kidney tubules (nephrons) which take days to regrow and repair. These cells then reestablish the high osmotic gradient in the kidney pyramids that enable concentration of urine. Until the cells regrow and the osmotic gradient is reformed, urine osmolality will be low. ...Read more

Slight foamy urine.spot urine test-protein 5mg/dl,creatinine 37mg/dl,albumin 2 mg/litre.Is it normal or proteinuria ?

Proteinuria: We generally calculate the urine protein to creatinine ratio and as long as the ratio is below 300 mg/g it is considered not significant (yours is only 135mg/g) so your proteinuria is not significant. But the Albumin level you mentioned, is it serum (blood) Albumin level? If yes, it is very low and unlikely! Please verify your Albumin level and it's source (blood or urine) . ...Read more
