BNP Chairperson Khaleda Zia underwent health check-ups at Evercare Hospital in the capital on Monday.
She arrived at the hospital from her Gulshan residence around 5:35pm and stayed there for an hour and a half, said her media wing member Sayrul Kabir Khan.
He said the BNP chairperson underwent several tests at the hospital as per the advice of her medical board, UNB reported.
The BNP chief left the hospital around 7:13pm and reached her residence at 8:22pm, he said.
Khaleda's personal physician, AZM Zahid Hossain, said the medical board formed earlier, led by Prof Shahabuddin Talukder, advised her to go for the health check-ups at the hospital.
"She underwent various necessary medical tests at the hopital. The test reports will be available by Tuesday,” he said.
Zahid said the medical board will decide the next course of her treatment after assessing the reports.
When asked about Khaleda Zia's physical condition, he said: "Her condition is as before. It remains unchanged.”
Khaleda, a 77-year-old former prime minister, has been suffering from various ailments, including liver cirrhosis, arthritis, diabetes, kidney, lung, heart, and eye problems.
She has received treatment at the same hospital six times since she was infected with Covid-19 in April 2021.
In November 2021, Khaleda Zia was diagnosed with liver cirrhosis.
On June 10, the BNP chief suffered a heart attack due to a 95% blockage in her left artery and a stent was installed the following day.
Doctors also found two more blocks in her blood vessels, but they could not remove them due to her health complications.
Khaleda was sent to the Old Dhaka Central Jail as a lower court sentenced her to five years' imprisonment in the Zia Orphanage Trust corruption case on February 8, 2018. Later, she was found guilty in another corruption case the same year.
Amid the coronavirus outbreak, the government temporarily freed Khaleda Zia from jail through an executive order suspending her sentence on March 25, 2020, with conditions that she would stay at her Gulshan house and would not leave the country.
