Harrington Onsite Drug TestingLogo Design Contest

So far the one we like the most is #48. We want people to see the "Onsite Drug Testing" 1st then see the Harrington part. Is there a way you can help draw attention to "Onsite Drug Testing?" Also can you make the image a little stronger in presence? We want something that stands out and will be easy to recognize. You've got some great stuff. Thanks

We like #43. Can you give a more 3-d quality to the symbol? Thanks!
