The present disclosure relates to use of a reagent for the lysis of erythrocytes, a method of lysing erythrocytes and a kit comprising the reagent. 1. A reagent for the lysis of erythrocytes , the reagent being an aqueous solution comprising HEPES ((4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) , NH/NH , a chelating agent and optionally CO/CO , wherein the final concentration during lysis of erythrocytes is in the range offrom 2.5 mmol/l to 12 mmol/l HEPES,{'sub': 4', '3, 'sup': '+', 'from 60 mmol/l to 120 mmol/l NH/NH,'}from 0.04 mmol/l to 0.8 mmol/l chelating agent, and{'sub': 3', '3, 'sup': 2−', '−, 'from 0.15 mmol/l to 0.8 mmol/l CO/CO, if present.'}2. The reagent of claim 1 , wherein the final concentration during lysis is in the range offrom 3 mmol/l to 11 mmol/l HEPES, preferably from 3 mmol/l to 10 mmol/l HEPES, more preferably from 3.5 mmol/l to 4.5 mmol/l HEPES,{'sub': 4', '3', '4', '3, 'sup': +', '+, 'from 70 mmol/l to 100 mmol/l NH/NH, preferably from 80 mmol/l to 85 mmol/l NH/NH,'}from 0.05 mmol/l to 0.5 mmol/l chelating agent, preferably from 0.06 mmol/l to 0.2 mmol/l chelating agent, more preferably from 0.07 mmol/l to 0.1 mmol/l chelating agent, and/or{'sub': 3', '3', '3', '3', '3', '3, 'sup': 2−', '−', '2−', '−', '2−', '−, 'from 0.3 mmol/l to 0.6 mmol/l CO/CO, preferably from 0.3 mmol/l to 0.5 mmol/1 CO/CO, more preferably from 0.35 mmol/l to 0.45 mmol/l CO/CO, if present.'}3. The reagent of claim 1 , wherein the chelating agent is ethylene diamine tetraacetic acid (EDTA).4. The reagent of claim 1 , wherein the pH of the reagent is in the range of from 6.4 to 7.7 claim 1 , preferably 6.7 to 7.4 claim 1 , more preferably 6.8 to 7.3.5. The reagent of claim 4 , wherein the pH is maintained in the range of from 6.4 to 7.7 claim 4 , preferably 6.7 to 7.4 claim 4 , more preferably 6.8 to 7.3 during lysis of erythrocytes.6. A method of lysing erythrocytes claim 4 , the method comprisinga) providing a sample comprising erythrocytes;{'claim-ref': [{'@ ...
