SERIAL DILUTION: PROBLEM SOLVING. Set up five (5) tubes on the test tube rack and label them 1-5. Place 0.9 ml of saline to tube #1 and 0.5 ml of saline to tubes #2-5. Add 0.1 ml of patient's serum to tube #1, mix and transfer 0.5 ml of the mixture to tube #2. Then, mix and transfer 0.5 ml of the mixture to tube # 3. Mix and continue dilutions through tube #5. Discard 0.5 ml from tube #5. Finally, add 0.5 ml of the reagent to each tube # 1-5. Compute for the initial dilution of tube #1 and final dilution of tube #5. Show your computation and encircle your final
