Possible False Positive Heart Fatty Acid Binding Protein in Patient Who Has a High Level of Creatinine Kinase Kreatin Kinaz Düzeyi Yüksek Olan Hastalarda Heart Fatty Acid Binding Protein Hatalı Olarak Pozitif Olabilir

Heart fatty acid binding protein (H-FABP) is a new marker with a low molecular weight which indicates early myocardial tissue injury (1, 2). Various studies have shown that H-FABP becomes positive earlier than troponins and is more sensitive than myoglobin (3-5). Besides, the H-FABP found in skeletal muscle is approximately 10-20% of the concentration of H-FABP in heart muscle (6). Recently, we have observed 3 patients who had high creatinine kinase (CK) and H-FABP levels for various reasons.
