# Title: SGOT (AST) Liquid Stable Reagent Kit 50 ml – Modified IFCC Kinetic Method ## Description: Swemed SGOT (AST) Liquid Stable Reagent Kit 50 ml The Swemed SGOT (AST) Liquid Stable Reagent Kit 50 ml is a professional clinical biochemistry reagent intended for quantitative determination of Aspartate Aminotransferase (AST), also known as SGOT, using the Modified IFCC kinetic method. Swemed’s official SGOT literature describes the assay as a kinetic UV method in which AST catalyses transfer of an amino group from L-aspartate to α-ketoglutarate, producing oxaloacetate and L-glutamate. The oxaloacetate then reacts with NADH in the presence of malate dehydrogenase, and the resulting decrease in absorbance at 340 nm is proportional to SGOT/AST activity in the sample. SGOT/AST is an important enzyme found in tissues including the liver, heart, skeletal muscle and kidneys. Its measurement is commonly included in liver function testing and broader clinical chemistry enzyme panels. This product is intended for professional in vitro diagnostic use only in pathology laboratories, diagnostic centres, hospitals and clinical chemistry laboratories.

Key Features Swemed Diagnostics SGOT / AST Reagent Kit Pack size: 50 ml Modified IFCC kinetic method UV measurement at 340 nm Liquid stable two-reagent system Suitable for routine AST / SGOT activity measurement Working reagent prepared using 4 parts R1 + 1 part R2 Working reagent stability: 7 days at 15–25°C Working reagent stability: 4 weeks at 2–8°C Linearity up to 300 U/L Suitable for professional liver and enzyme-profile testing For in vitro diagnostic use only Also available as part of the Swemed LFT Reagent Combo Kit Key Benefits Modified IFCC Method The Swemed SGOT assay uses a Modified IFCC kinetic method, providing a standardised enzymatic approach for routine AST activity measurement. Liquid Stable Reagent System The product uses a two-reagent system designed for routine laboratory use and working-reagent preparation. Useful Working Reagent Stability The manufacturer states that prepared working reagent remains stable for: 7 days at 15–25°C 4 weeks at 2–8°C Suitable for Routine Liver Function Testing SGOT / AST is commonly measured together with SGPT / ALT, bilirubin, alkaline phosphatase, albumin and total protein as part of liver function assessment. Professional Laboratory Application The method is suitable for trained laboratory personnel using compatible semi-automated or automated chemistry systems after analyser validation. Intended Use The Swemed SGOT / AST Reagent Kit is intended for quantitative determination of Aspartate Aminotransferase activity in professional clinical chemistry laboratories. The official Swemed insert specifies serum as the specimen and recommends fresh, clear, non-haemolysed serum. Swemed’s biochemistry listing also associates SGOT with serum/plasma including EDTA and heparin plasma, so the actual specimen type should follow the current kit insert supplied with the product and the laboratory’s validated method. Test Principle SGOT / AST catalyses the following reaction: L-Aspartate + α-Ketoglutarate → L-Glutamate + Oxaloacetate The oxaloacetate formed then reacts with NADH in the presence of malate dehydrogenase (MDH): Oxaloacetate + NADH + H+ → L-Malate + NAD+ The rate at which NADH is oxidised to NAD+ is measured as a decrease in absorbance at 340 nm, and this rate is proportional to AST activity in the sample. Reagent Composition Component Manufacturer Specification Reagent 1 Tris Buffer pH 7.8 – 6 g/L Reagent 1 L-Aspartate – 30.5 g/L Reagent 1 LDH – 4 kU/L Reagent 1 MDH – 700 U/L Reagent 2 α-Ketoglutarate – 3.4 g/L Reagent 2 NADH – 1.1 g/L The manufacturer also states that the reagents contain sodium azide 0.95 g/L as preservative. Reagent Preparation Prepare the working reagent by mixing: 4 parts Reagent R1 + 1 part Reagent R2 Alternatively, the Swemed insert states that 0.8 ml R1 + 0.2 ml R2 may be used directly instead of 1 ml of pre-mixed working reagent during the assay. The working reagent should have an absorbance above 1.0 against distilled water at 340 nm. Reagent falling below this level should not be used. Working Reagent Stability Storage Condition Stability 15–25°C 7 days 2–8°C 4 weeks Technical Specifications Test Parameter Manufacturer Specification Parameter SGOT / AST Method Modified IFCC Mode Kinetic Wavelength 340 nm Unit IU/L Temperature 37°C Reaction Slope Decreasing Reagent Volume 1000 µl Sample Volume 100 µl Delay Time 60 seconds Reaction Time 180 seconds Reading Interval 60 seconds Blanking Water Blank Factor 1746 Linearity 300 U/L These values are listed in Swemed’s quick-reference section. Manual Assay Procedure Component Macro Method Semi-Micro Method Reagent R1 + R2 800 µl + 200 µl 400 µl + 100 µl Sample 100 µl 50 µl Mix well and read the initial absorbance after 1 minute. Continue readings at approximately 1-minute intervals for 3 minutes, then calculate the mean absorbance change per minute. Calculation SGOT / AST (U/L) = ΔA/min × 1746 Measuring Range and Linearity The manufacturer states a linearity of 300 U/L. When the reaction rate exceeds the stated measuring range, Swemed describes dilution of the sample 1 + 9 with 0.9% NaCl, followed by multiplication of the obtained result by 10. Specimen Requirements The official product insert recommends: Fresh serum Clear sample Non-haemolysed specimen This is particularly important because red blood cells contain AST, and haemolysis may cause falsely elevated results. Specimen Stability According to the Swemed product literature, SGOT / AST in serum is reported stable for: Storage Condition Stability 15–30°C 4 days 2–8°C 10 days −20°C 2 weeks Interference Information The manufacturer reports that under the evaluated conditions: Bilirubin up to 18 mg/dL Haemoglobin up to 300 mg/dL had negligible effect on the assay. However, haemolysed samples should still be avoided because red cells contain AST and can produce misleadingly elevated results. Manufacturer Reference Range Group Manufacturer Reference Women < 31 U/L Men < 32 U/L Swemed also advises that each laboratory establish or validate reference intervals appropriate for its own patient population. Why SGOT / AST Testing Is Important AST is present in several tissues, particularly: Liver Cardiac muscle Skeletal muscle Kidneys AST activity may rise when cells in these tissues are injured. SGOT / AST testing may therefore form part of laboratory investigations related to: Liver injury Hepatitis Cirrhosis Muscle injury Cardiac-related investigations Acute pancreatitis Renal disease Routine liver-function profiles Because AST is not liver-specific, results should be interpreted together with other parameters such as ALT / SGPT, bilirubin, alkaline phosphatase, albumin and clinical findings. SGOT / AST in a Liver Function Profile Test Laboratory Relevance SGOT / AST Hepatic and extra-hepatic enzyme assessment SGPT / ALT More liver-associated transaminase Bilirubin Total Bilirubin metabolism Bilirubin Direct Conjugated bilirubin assessment Alkaline Phosphatase Hepatobiliary and bone-related enzyme Albumin Liver synthetic function / nutritional assessment Total Protein Protein status GGT Hepatobiliary enzyme where included Storage and Handling Swemed states that the reagents should be: Stored at 2–8°C Protected from light Protected from contamination Not frozen Used only within the stated shelf life The manufacturer also advises against using reagent if the initial absorbance at 340 nm falls below the stated acceptable level or if performance requirements are not met. Safety and Precautions Laboratory personnel should: Wear suitable gloves Use eye and face protection Avoid skin and mucous membrane contact Avoid ingestion Follow current Good Laboratory Practice Handle sodium-azide-containing reagent appropriately Dispose of reagents according to institutional procedures Who Can Buy This Product?
