** Shares in Netherlands-based biotechnology company Qiagen QIA.DE fall 7%, heading for their worst session in more than five years, after full-year outlook cut, weaker Q1 results
** Qiagen now expects FY revenue growth of between 1% and 2% vs 5% before; adjusted diluted EPS to be at least $2.43 vs $2.51 seen before
** Outlook downgrade is driven by weaker QuantiFERON immigration testing demand, ongoing caution among U.S. life sciences customers, and rising geopolitical uncertainty, the company says
** Q1 net sales were $492 million vs $500 million expected by Vara consensus
** The Q1 print was a surprise, Jefferies says
** "Absent notable prudence on the guide, expect the stock to be down," the broker says
** Including Tuesday's loss, the stock is down 22% this year
