"Thank you SingleSource Services for your drug screens! They are excellent! We use the 10 panel with the adulterant testing. Since we screen candidates regularly for our clients, we need reliable drug screens. The I-Cups read quickly, are accurate, and most of all, do not leak! We can use them with confidence, presenting quality drug-free personnel. Thank you for the great drug screens and the exceptional customer service."
