What does diagnostic testing include?

Diagnostic tests are either invasive and non-invasive. Invasive diagnostic testing involves puncturing the skin or entering the body. Examples are taking a blood sample, biopsies, and colonoscopies. Non-invasive diagnostic testing does not involve making a break in the skin.

• Phonics Inventory.
• Running records.
• Intervention- or curricula-specific diagnostic tools.
• Word list reading (e.g., Dolch, Fry, curriculum sight word lists)

What is a diagnostic test accuracy study?

A diagnostic test accuracy study provides evidence on how well a test correctly identifies or rules out disease and informs subsequent decisions about treatment for clinicians, their patients, and healthcare providers.

How to calculate the probability of a diagnostic test?

Diagnostic Test Calculator Diagnostic Test Calculator This calculator can determine diagnostic test characteristics (sensitivity, specificity, likelihood ratios) and/or determine the post-test probability of disease given given the pre-test probability and test characteristics. Given sample sizes, confidence intervals are also computed.
