Unipath Ltd was a pharmaceutical company, subsidiary to Unilever and then Alere, specialising mainly in medical diagnostic kits related to women's reproductive health.
It subsequently diversified its product range to include more specialised test kits, primarily for the clinical market, in areas other than women's reproductive healthcare.
The product was a success, in part due to intensive advertising and held a majority market share in the UK by the end of the year.
The kit was designed for use in identifying the period of peak fertility in a prospective mother's menstrual cycle so that the optimal time for insemination leading to conception could be determined.
In 2007, Clearblue and other brands were folded into Swiss Precision Diagnostics (SPD) as a 50/50 joint venture between Alere and Procter & Gamble.
