Question

pick  5 Chemistryanalytes (Example: Troponin) and describe the following for each analyte:
1. Normal range
2. Units in which analyte is reported
3. Disease caused by increased or decreased value
4. Does Hemolysis affect the test result?
5. What color tube is required for the analyte testing

Answer 1

Chemistry analytes examples are Troponin, creatinin, calcium, chloride, Bilirubin.

A) Troponin:

1. Normal range: <14ng/L
2. Units in which analyte is reported: Nano grams/ Litre.
3. Disease caused by increased or decreased value: Increased troponin values indicate heart attack or injury to heart.
4. Does Hemolysis affect the test result?yes
5. What color tube is required for the analyte testing? Green/yellow top tube (plasma seperator)

B)Creatinin:

1. Normal range: 0.2 - 0.8mg/dl
2. Units in which analyte is reported: milligram/decilitre.
3. Disease caused by increased or decreased value: Renal failure
4. Does Hemolysis affect the test result? yes . It falsely decreases creatinine.
5. What color tube is required for the analyte testing? Green top tube.

C) Calcium:

1. Normal range : 8-10 mg/dL (2-2.5 mmol/L)
2. Units in which analyte is reported: mg/dL or mmol/L
3. Disease caused by increased or decreased value: Hypercalcaemia and Hypocalcaemia
4. Does Hemolysis affect the test result? Slight change
5. What color tube is required for the analyte testing? Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube; do not use oxalate, EDTA, or citrate plasma.

D)Chloride:

1. Normal range; 98-106mmol/L sd
2. Units in which analyte is reported: milli moles/litre
3. Disease caused by increased or decreased value: Hypochloremia with decreased chloride levels.
4. Does Hemolysis affect the test result? Sigificant effect but reained with in CLIA limits.
5. What color tube is required for the analyte testing? Green top (Li Heparin) tube.

E) Bilirubin:

1. Normal range: 0 to 0.4 mg/dL
2. Units in which analyte is reported: mg/dl
3. Disease caused by increased or decreased value: It indicates liver damage or jaundice.
4. Does Hemolysis affect the test result? test result decreased by hemolysis.
5. What color tube is required for the analyte testing? Red-top tube or green to tube.
