What should we do if protein urine is not match with 24 hour protein urine

Yesterday morning, a patient asked me, what’s the meaning of protein urine 2+, and 24 hour protein urine 0.2g?

Coincidentally, another asked me in the afternoon that which one should be believe, protein urine negative or 24 hour protein urine 0.8?

When we meet this case, we are full of doubts: is there something wrong with the test? Which one should I believe?

Here we can answer why two test have different result.

Reason 1: different time, different result.

The result will be different in different time, and as well as protein urine level. In the morning, it will be lower than normal, and the regular urine test often choose this period. So it is possible to find protein urine level high in other period but low in the morning test.

Solution: if you find the result is a little high, you can have a 24 hour urine test, this one is more correct.

Reason 2: different water ingestion.

Water ingestion will affect the urine test. And if you drink more water than you suggested, it will cause albumin level lower than it should.

Solution: before doing test, avoid over drinking water.

Reason 3: wrong test method.

Urine test has its limitation. Protein urine can be divide into various type, and some diseases will cause globlin increase, which is invisible to normal urine test.

Solution: if you can not make sure, ask doctors is the most effective method and normally, fallible test worth three times test.

All in all, if you feel something wrong with you, go to have some test, it will not cost you a good fortune but save you.
