Abstract
The invention relates to a method for preparing blood samples for detecting homocysteine and/or total folate and is characterized in that the blood sample is brought into contact with (a) at least one reagent for lysis of the blood cells, (b) at lease one inhibitor of the enzymes which produce and break down homocysteine, and optionally (c) at least one acid.
Claims11
A method of preparing blood samples for detecting homocysteine and/or total folate, wherein a blood sample is brought into contacts during or immediately after blood withdrawal, with:
- a) at least one reagent for lysis of blood cells,
- b) at least one inhibitor of enzymes which produce and break down homocysteine, wherein the reagent for lysis of blood cells and the at least one inhibitor of enzymes which produce and break down homocysteine are effective for stabilizing homocysteine levels in the blood sample.
A method of preparing blood samples for detecting homocysteine and/or total folate, wherein a blood sample is brought into contact, during or immediately after blood withdrawal, with:
- a) octyl phenol ethylene oxide condensate;
- and
- b) at least one inhibitor of enzymes which produce and break down homocysteine,
- wherein the octyl phenol ethylene oxide condensate and the at least one inhibitor of enzymes which produce and break down homocysteine are effective for stabilizing homocysteine levels in the blood sample.
A method of preparing blood samples for detecting homocysteine and/or total folate, wherein a blood sample is brought into contact, during or immediately after blood withdrawal, with:
- a) at least one reagent for lysis of blood cells;
- b) at least one inhibitor of enzymes which produce and break down homocysteine;
- and
- c) at least one additional acid;
- wherein the reagent for lysis of blood cells and the at least one inhibitor of enzymes which produce and break down homocysteine are effective for stabilizing homocysteine levels in the blood sample.
