Learning Outcome: At the end of the LABORATORY REPORT, the learner is expected to: 1. Efficiently perform the process of doing a capillary fragility test. 2. Know the clinical importance of performing a capillary fragility test for patients with bleeding disorders. EXPERIMENT NO. 6: CAPILLARY FRAGILITY TEST Principle: The capillary fragility test is also known as the Tourniquet test, Rumpel-Leede Test, Hess test. This test evaluates capillary integrity. It is used to aid in the clinical diagnosis of hemorrhagic fever syndromes such as Dengue Fever. Petechiae occur as a result of increased capillary fragility (microvessels easily rupture and a small amount of bleeding occurs in the skin) or thrombocytopenia (causing spontaneous bleeding in the skin). There are more accurate tests to indicate platelet count and function. Petechiae are small, round, nonraised red spits in the skin. Production of petechiae can be induced in patients who have increased capillary fragility or thrombocytopenia. There are two methods of inducing petechiae. The most common is with positive pressure. A blood pressure cuff is applied to an extremity and inflated above venous pressure. The second way is with negative pressure. A suction cup is applied to an area of skin for a particular period of time. Patients with thrombocytopenia, poor platelet function, or purpura will develop more than 10 petechiae per square inch of skin. The number of petechiae can be graded from few with confluent (1 to 4). Indications: Assessment of platelet-vessel wall interactions. Reference Range: Negative or 1+. Within a radius of 2.5 cm: Females = 10 or less petechiae Males = 5 or less petechiae REFERENCES: Turgeon, M. L. (1993). Clinical hematology: Theory and procedures. Boston: Little, Brown. Pagana, K.

Materials: PROCEDURE CAPILLARY FRAGILITY TEST (Rumple Leede Test) 1. Blood Pressure Apparatus 2. Stopwatch Procedure: 1. Apply Blood Pressure cuff to the upper arm. 2. Initiate the BP cuff at a pressure halfway between the systolic and diastolic pressure and leave it for 5 minutes. 3. Remove the BP cuff from the arm and examine the forearm, hand and finger for petechia. 4. Report as follows: 0-10 petechia 11-20 petechia 21-50 petechia 51 and above +1 + 2 +3 +4
