Transient microalbuminuria may occur with a number of conditions. The diagnosis of diabetic nephropathy requires at least 2 out of 3 urine specimens showing microalbuminuria over a 6 month period.
Causes of a transient microalbuminuria:
(1) fever
(2) urinary tract or other infection
(3) moderate to severe hypertension
(4) recent strenuous exercise (within past 24 hours)
(5) congestive heart failure
(6) transient severe hyperglycemia
where:
• The Standards from 2004 included hematuria as a cause. Some hematuria may occur with a urinary tract infection.
• Congestive heart failure is associated with high venous pressures.
If microalbuminuria is present and one or more of these conditions are identified, then repeat testing once the condition has cleared.
