The family story Olivia, a blond teen, is resoundingly beating her male tennis opponent, Ned. She is new in town and jokes that her partner went easy on her to make her feel welcome. From nowhere, a tennis ball cuts across their court. The dark-eyed brunette who hit it, Diana, stares at them. Olivia seems stunned into silence. Diana sneers at her and says, “Any day now.” Olivia hits the ball back to her, almost directly into her face. “What was that all about? You know Diana Morrison?” Ned asks. “I used to, back when I lived in Granville the first time,” Olivia answers. “Back then we were friends. It was like a million years ago.” As they walk away, we hear Diana’s tennis coach screaming, “Diana, Diana! Somebody help Diana, please!” “Is she OK?

- INTERPRETATION OF RESULIS NEGATIVE: Two lines appear. One colored line should be in the control region (C), and another apparent colored or faded color line adjacent should be in the test region (T). This negative result indicates that the drug concentration is below the detectable level. POSITIVE: One colored line appears in the control region (C). No line appears in the test region (T). This positive result indicates that the drug concentration is above the detectable level. INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test using a new test panel. If the problem persists, discontinue using the lot immediately and contact your local distrībutor.
