No, a little leaking won't alter the test results. You're measuring the concentration of certain molecules in the water. Yes, they're in parts per million, but when you leak a little bit of the solution, you're leaking the solute and the solvent (and the test chemicals) roughly equally. You'd need to remove a significant portion of the solute without removing any solvent (or vice versa) to seriously affect the results. It's not an issue, trust me.
