The presence of proteinuria (>300 mg/d) represents an important factor in the diagnosis and evaluation of the pregnant patient with an hypertensive disorder. The 24 hour collection of urine for proteinuria is the gold standard for the diagnosis of the condition and allows the physician to determine if an hypertensive disorder is related directly or not to the gestation.
The problem is the time it takes and the technical difficulties related to the sample collection. An alternative is the quantification of protein and creatinine in a random sample of urine. We seek to evaluate if this method is as affective as the gold standard in the diagnosis of proteinuria (>300 mg/d).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Hypertensive disorder of pregnancy | Other | Patients with an hypertensive disorder of pregnancy (28 weeks or more of gestation)will collect a random sample of urine for a spot test (protein/creatinine ratio) and urine for 24 hours. The level of proteinuria will be determined in this sample. |

| Measure | Description | Time Frame |
|---|---|---|
| Sensitivity and Specificity | The number of patients with a 24 hour urine collection with a proteinuria > 300mg will be compared with the number of patients with a Spot Test (protein/creatinine ratio in a random urine sample) > 0.2 (equivalent to the 24 hour test > 300 mg). This value will be used to calculate the Sensitivity and Specificity of the spot test. | Six months |
| Measure | Description | Time Frame |

| Positive and Negative Predictive Value | The number of patients with a 24 hour urine collection with a proteinuria > 300mg will be compared with the number of patients with a Spot Test (protein/creatinine ratio in a random urine sample) > 0.2 (equivalent to the 24 hour test > 300 mg). This value will be used to calculate the positive and negative predective value of the spot test. | six months |
