De Discretest

- A new urine test for detection of the midcyclic LH peak (Discretest) was performed on 26 women in 47 menstrual cycles. The method was checked in the laboratory.

At the given colour change at ≥ 50 IU LH per litre of urine, a sensitivity of 71.4 and a specificity of 92.6 were found in morning urine.

Conclusion: this ‘do-it-yourself’ method can be an asset in cases where prediction of ovulation is desired with a view to conception.
