Aim: Thorough diagnostics are a prerequisite for the optimal treatment of Alzheimer’s disease (AD). Biomarker-based diagnostics are standard in academia, data on practitioners’ diagnostic workups is scarce. Materials & methods: Surveys in German and US healthcare providers (HCP) were conducted regarding diagnostics in presumed AD patients. A subsample of 153 German and 88 US professionals was analyzed in detail. Results: Fewer German physicians conduct AD diagnostics themselves compared with US colleagues (67% vs 99%; p < 0.0001). German doctors more often order diagnostics at other institutions (65% vs 45%; p < 0.005). No significant differences were found regarding the type of diagnostics ordered at other institutions. Conclusion: Diagnostic routines for suspected AD patients differ between German and US–American healthcare providers. Plain language summary: It is important to conduct the best-possible tests to come to a correct diagnosis of Alzheimer’s disease (AD). This ensures choosing the optimal treatment. In academic surroundings such as specialized memory clinics, so called biomarkers (found for example in blood) are an important component in finding the correct diagnosis. However, there is limited data on the methods healthcare providers (HCP) use in their everyday clinical practice. With this study, we aimed to get a clearer picture of the differences in the diagnostic routines for potential AD patients implemented by HCPs in two highincome countries, Germany and the USA. We conducted two surveys in 500 German and 100 US HCPs on their AD-diagnostic routines. A comparable subsample of 153 German and 88 US professionals was analyzed in detail.We found that fewer German physicians conduct AD diagnostics themselves compared with their US–American colleagues (67% vs 99%). The other way around, German doctors more often order diagnostics at other institutions (65% vs 45%). However, there were no significant differences in the type of diagnostic procedures ordered at other institutions. In conclusion, diagnostic routines for suspected AD patients differ between German and US–American healthcare providers, such as biomarkerbased diagnostics, which German physicians significantly perform less often.

Test Type Analysis

The COVID-19 diagnosis market by test type is segmented into molecular tests, antigen tests, and antibody tests. Molecular tests, including RT-PCR, have been the gold standard for COVID-19 diagnosis due to their high sensitivity and specificity. These tests detect the virus's genetic material, making them highly accurate in identifying active infections. The widespread adoption of molecular testing has been driven by the urgent need for precise diagnosis, especially in the early stages of infection when viral loads are high. Moreover, continuous advancements in molecular diagnostic technologies have reduced the turnaround time and increased the throughput, making these tests more accessible and efficient.

Antigen tests offer a rapid and cost-effective alternative to molecular tests. These tests detect specific proteins from the virus, providing results in a shorter time frame, often within minutes to an hour. While antigen tests are generally less sensitive than molecular tests, their ability to deliver quick results has made them invaluable in settings where rapid decision-making is critical, such as airports, schools, and workplaces. The growing demand for mass testing and the need to quickly identify and isolate infected individuals have significantly boosted the adoption of antigen tests worldwide.

Antibody tests, also known as serological tests, detect the presence of antibodies in the blood, indicating past exposure to the virus. These tests are crucial for understanding the spread of the virus within populations and for identifying individuals who may have developed some level of immunity. While not typically used for diagnosing active infections, antibody tests have played a vital role in epidemiological studies and vaccine efficacy assessments. The development of highly sensitive and specific antibody tests has improved the accuracy of these assessments,
