ABSTRACT
This review will discuss the investigation of infertility, with emphasis on laboratory testing and reference to the value of other investigations, including clinical and radiological. The role of laboratory investigations is viewed within an appropriate clinically directed pathway that includes medical, surgical, and social history together with environmental factors. Because embryology and assisted reproduction techniques are developing rapidly and produce continuous changes in everyday practice, this article gives a critical review of the plethora of tests that are currently used.

The duration of lochia and its association with a number of obstetric variables was studied in 236 women. Each woman completed a diary sheet describing the colour and duration of her lochia for up to 60 days post partum. The phases of lochia were divided according to the classical description; lochia rubra, serosa and alba. The median total duration of lochia was 33 days, lochia rubra 4 days and lochia serosa 22 days. Lochia persisted to 60 days in 13% of women. The duration of lochia was shorter in parous women and women with smaller babies.

Patients with primary varicose veins were examined by a combination of the standard tourniquet test with detection of reflux by Doppler ultrasound. Results were compared with standard clinical tests: impulse or thrill at the saphenous opening on coughing, tap impulse at the groin, and the 'Trendelenburg' tourniquet test. The state of competence of the saphenofemoral junction was noted at operation. One hundred and sixty-one limbs of 105 patients were studied. The saphenofemoral junction was incompetent in 132/161 limbs (82 per cent) and was judged competent in 29/161 limbs (18 per cent). The combined Doppler and tourniquet test assessed the saphenofemoral junction correctly in 82 per cent of limbs and was more accurate than all the other tests. The test had good sensitivity (0.9) but poor specificity (0.45). Poor specificity was a feature of all the tests except for thrill which was a highly insensitive test. The combined Doppler and tourniquet test appears to be the most simple, rapid and accurate means of detecting saphenofemoral incompetence.
