No point in doing a 24 hour urine with negative dipstick? Au contraire, mon ami!

Much of the time that there is _no_ protein on dipstick there will actually be _greater than 300 mg in 24 hours_ when HTN is present.

Am J Obstet Gynecol. 1994 Jan;170(1 Pt 1):137-41, just for example.

IMHO, it's quite frequently worth sending the 24 hour urine when the dip is negative - less so when significantly positive, unless the patient is so severely preterm that you need to dot every i before recommending delivery.

Wonder if Andrew's patient was dip neg or trace during the second 24 hour urine collection?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
