Once I posted my answer, I realized that you might be looking for something like this instead:

NRF_RTCx->TASK_START;  
tick = NRF_RTCx-> COUNTER;  
NRF_RTCx->TASK_CLEAR;

Take look at this post, that might be useful.
Also, you can take a look at my answer in this post about converting ticks to time.

Hi Omar!

Did you take a look at the RTC example in our SDK?
The Real Time Counter Example enables the real-time clock with a TICK frequency of 8 Hz. The TICK interrupt handler clears the interrupt request and toggles LED 1. The COMPARE0 handler clears the interrupt request and sets LED 2 to 1.

If you take a look at the RTC driver in the infocenter you should find all the information you need.
The nrf_drv_rtc_counter_get() function can be used to retrieve the current counter value.
You can use the nrf_drv_rtc_counter_clear() function to clear the counter value.

Let me know if you still have any questions.
Best regards,
Joakim.
