Questions: Which of the following techniques involve drawing a sample of blood for laboratory analysis? More than one answer may be correct. MSA Muscle biopsy Genetic testing EMG Creatine kinase levels

The techniques that involve drawing a sample of blood for laboratory analysis are:

• Genetic testing: This often involves analyzing DNA, which can be obtained from a blood sample. Therefore, genetic testing can involve drawing blood.

• Creatine kinase levels: Measuring creatine kinase levels is a blood test used to assess muscle damage or disease. This test requires a blood sample.

Explanation for each option:

1. MSA (Muscle Strength Assessment): This is typically a physical test to assess muscle strength and does not involve drawing blood.

2. Muscle biopsy: This procedure involves taking a small sample of muscle tissue for examination, not blood.

3. Genetic testing: Correct. This can involve drawing blood to obtain DNA for analysis.

4. EMG (Electromyography): This test measures the electrical activity of muscles and nerves and does not require a blood sample.

5. Creatine kinase levels: Correct. This test involves drawing blood to measure the level of creatine kinase, an enzyme that can indicate muscle damage.

In summary, the correct answers are "Genetic testing" and "Creatine kinase levels."
