Після того як лікар перевірив пацієнта, він призначив аналіз крові.

It introduces a time clause and means after in the sense of after X happened.

Literally, the parts are:

• після = after
• того = that / of that
• як = how / as / when in this kind of structure

As a whole, після того як works like one connector: after. Ukrainian often uses multi-word connectors like this.

Because Після того як лікар перевірив пацієнта is a subordinate clause, and it comes before the main clause він призначив аналіз крові.

So the comma marks the boundary between:

• the time clause
• the main action

This is very similar to English: After the doctor examined the patient, he ordered a blood test.

They are past tense masculine singular forms.

That matches a male subject:

• лікар перевірив = the doctor checked/examined
• він призначив = he ordered/prescribed

Compare:

• masculine: перевірив, призначив
• feminine: перевірила, призначила
• plural: перевірили, призначили

So the ending helps show who performed the action.

Because пацієнта is the accusative singular form of an animate masculine noun.

The verb перевірив takes a direct object, and пацієнт is a person, so in the accusative singular it changes like this:

• nominative: пацієнт
• accusative: пацієнта

This is a very important Ukrainian pattern: for animate masculine nouns, the accusative often looks like the genitive.

This phrase contains two different case relationships:

• аналіз is the direct object of призначив, so it is in the accusative
• but for an inanimate masculine noun, accusative singular usually looks the same as nominative, so it stays аналіз

Then:

• крові is genitive singular
• it means of blood

So аналіз крові literally means analysis of blood, which is the normal Ukrainian way to say blood test.

In normal interpretation, він refers to лікар, not пацієнт.

However, grammatically, there is some potential ambiguity because both лікар and пацієнт are masculine singular nouns. In real context, logic tells us that the doctor is the one who would order the blood test.

If you want to remove even the slight ambiguity, Ukrainian could repeat the noun:

• Після того як лікар перевірив пацієнта, лікар призначив аналіз крові.

But that sounds a bit repetitive, so він is natural.

Not always. Ukrainian often allows the subject to be omitted when it is clear from context.

So you could also say:

• Після того як лікар перевірив пацієнта, призначив аналіз крові.

Because призначив is masculine singular, the listener can infer he. Still, with two masculine nouns already in the sentence, some speakers may prefer він for clarity, even if it does not remove ambiguity completely.

Because the sentence presents two completed actions in sequence:

1. the doctor finished examining the patient
2. then he ordered the blood test

The perfective forms перевірив and призначив fit that completed, one-time sequence very well.

If you used imperfective forms such as перевіряв or призначав, the meaning would shift more toward process, repetition, or background action, which would sound less natural in this sentence.

Yes. Ukrainian word order is fairly flexible, although the most neutral version is often the one you have here.

For example, you could also say:

• Лікар призначив аналіз крові після того, як перевірив пацієнта.

That version puts the main action first and the time relationship afterward. The meaning stays almost the same, but the emphasis changes a little.

Because Ukrainian has no articles.

English needs the doctor, the patient, a blood test or the blood test, but Ukrainian usually expresses that information through context instead of separate words.

So:

• лікар can mean the doctor or a doctor
• пацієнта can mean the patient or a patient
• аналіз крові can mean a blood test or the blood test

The exact interpretation comes from context.

It is understandable and correct, but depending on context, some speakers might choose a more medical verb such as оглянув.

Compare:

• перевірив пацієнта = checked the patient
• оглянув пацієнта = examined the patient, especially in a medical sense

So your sentence is fine, but оглянув may sound a bit more specifically clinical.

The main stresses are:

• пІсля
• тогО
• як
• лікАр
• перевірИв
• паціЄнта
• вІн
• призначИв
• аналІз
• кровІ

Stress is important in Ukrainian because it is not always predictable, so it is worth learning words together with their stress.
