Apparatus (10) for testing blood comprising a single substantially rectangular transparent plastics moulding. The apparatus has a hollow (12) connected by five capillaries (14) to chambers (16A-E) each of which contains an impregnated permeable membrane. Further capillaries (18) lead from the chambers (16) decreasing in diameter along their length to respective indication chambers (20A-E). Each of the chambers (20) is such that, when blood passes thereinto either an indication thereon is obscured or an indication is provided on a previously plain background. Each of the chambers (20) is connected to atmosphere by vent capillaries (22). |
