Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A method for detecting and measuring chronic alcohol consumption constituting alcohol abuse in a human patient comprising: a. obtaining a human blood sample from said patient; b. isolating a fraction of said blood sample which contains glycosylated hemoglobins; c. measuring the amount of said glycosylated hemoglobins as a percentage of the total amount of hemoglobin in said sample; d. providing a measurement of the amount of glycosylated hemoglobins in a blood sample of a known alcohol abuser, the measured amount of the glycosylated hemoglobins of said abuser being more than about 6% of the total hemoglobin in said blood sample of the abuser; and e. comparing the measurements of steps (c) and (d) whereby a comparison of said measurements determines the alcohol abuse of said patient.
Claim 2
Independent Claim
126 words
A method for detecting and measuring chronic alcohol consumption constituting alcohol abuse in a human patient comprising: a. obtaining a human blood sample from said patient; b. isolating a fraction of said blood sample which contains glycosylated hemoglobins; c. measuring the amount of said glycosylated hemoglobins as a percentage of the total amount of hemoglobin in said sample; d. providing a measurement of the amount of glycosylated hemoglobins in a blood sample of a known alcohol abuser, the measured amount of the glycosylated hemoglobins of said abuser being more than about 6% of the total hemoglobin in said blood sample of the abuser; and e. comparing the measurements of steps (c) and (d) whereby a comparison of said measurements determines the alcohol abuse of said patient.
Claim 3
Dependent Claim
13 words
The method of claim 1, wherein the patient's blood sample comprises anticoagulated blood.
Claim 4
Dependent Claim
40 words
Method of claim 1, wherein step (b) thereof further comprises: (i) exposing the red blood cells of step (i) hereof to osmotic shock, whereby a hemolysate is prepared; and (ii) separating the hemoglobin adducts of step (i) hereof by chromatography.
Claim 5
Dependent Claim
17 words
The method of claim 1, wherein the measurements of step (c) are performed by a colorimetric assay.
Claim 6
Dependent Claim
13 words
The method of claim 4, wherein the assay is performed at 421 nm.
